Someone had recently asked me what my favorite science experiments were when I was in High School and after giving it some thought, I've got my list ready! I was always a very visual learner and these were the experiments that stuck in my head:
10. Free Fall Tube demonstration - evacuating the air from a tube and watching the feather and the coin fall at the same rate.
9. Toothpick Bridge - although I was never very good at this, the engineering shown by some of my classmates was impressive. We had to make a bridge using only toothpicks and glue that must be a specific size and would be tested with weights to see how much it would hold.
8. Dog Mouth/Human Mouth - I was crushed to find out that the petri dish swabbed from my pug's mouth had significantly less growth on it than one swabbed in my own mouth...especially after years of watching him eat any kind of garbage he could get into!
7. Pie in the Face - a great high school physics teacher of ours would allow us to throw a pie in his face if we could correctly figure the speed of said pie in the moment before impact.
6. Table Cloth (Inertia) - I think we all did this as a youth....yank the tablecloth swiftly enough so that the china didn't move but the table cloth came out!
5. Physics of a Curveball - I was fascinated to learn about the rotation and the laces on the ball causing a baseball to curve.
4. Blow up the Peep! - Stick one of those marshmallow peeps in a bell jar and evacuate the air and watch it grow!
3. Toilet vs. the phone - I still to this day wipe my office phone quite often after seeing how much more bacteria was on my phone compared to the toilet seat!
2. Watermelon Toss - In High School Physics, we took into account wind, height, weight, etc and place a hula hoop in the parking lot and rolled a watermelon off of the top of the bleachers. It was amazing to see it land exactly as we predicted with a very messy result!
1. Physics Day - Our local amusement park, Six Flags Great America, would host Physics day each year and we would be given handouts where we had to calculate the speed, acceleration, etc of many of the rides. Lots of fun topped off by riding a few roller coasters. There are few better ways than to keep the interest of a high school student!
Which ones were your favorites??

New Products from United Scientific
I'm pleased to announce some new products now available from United Scientific:
This economical Stirling Engine runs by exploiting the heat flow generated by the small temperature difference between room temperature and a cup of hot water or ice. It is a classic illustration of converting heat energy into mechanical work using a thermodynamic cycle. The engine runs at about 150rpm when used with cup of hot water. Additional information available upon request. Includes a detailed activity guide. 
A basic, inexpensive Fan Cart powered by two AA size batteries (not included) demonstrates Newton’s principal of action and reaction. The batteries are contained in the removable power unit and the fan is controlled by a switch. The propeller delivers a thrust of about 88mN, accelerating the cart at 0.4 m/s². A transparent plate can be attached to show the effect of reversing the airflow.
United plans to introduce many more products for 2012! Please contact me for dealer pricing and digital images!
Have a great day!

Solar Car
This economical demonstration solar car can be powered by a solar cell or a rechargeable battery (AA size, not included. Alkaline batteries are not suitable). Battery can be recharged from the solar cell, demonstrating an electricity storage system for solar power. The solar cell can be tilted to maximize solar input, features an on/off and select function switch, and includes two binding posts to measure output. All working parts are visible through the clear molded housing. Includes an activity guide
Spillnot
The design of the SpillNot™ uses the principles of Newtonian physics to keep the liquid in the container. The flexible handle and the location of the suspension point above the center of the tray ensure that the forces on the liquid are always directed towards the supporting tray, even when the tray is in motion. The sideways forces that are usually responsible for spills are not transmitted to the tray by the flexible handle and the radial forces generated during swinging motion only pin the liquid into the container more firmly. An inexpensive demonstration to intrigue students and challenge their analytical powers! Includes a detailed activity guide.

Top Ten Ways playing team sports helps students!
As a father of a 5 year old and a 7 year old, this is my first summer watching my boys play team sports. They played T Ball earlier in the summer and they play flag football now. Its great that they are able to play on the same team for logistics, but I'm sure that ends in the next couple of years. I've watched our boys take a lot from their team sports experience and I'd like to share with other parents what I've seen:
10. Teaches kids to "be on time" - both coaching staffs were very adamant that practice started at a certain time and held all kids and parents accountable. As the seasons progress, I've noticed our boys getting themselves ready for practice at the appropriate time.
9. Builds friendships - This is an easy one as we've seen our boys make lots of new friends, attend birthday parties, and basically just smile when they see their friends outside of practice/games.
8. Hand/Eye Coordination - Too many children are perfecting their hand/eye coordination by means of Xbox and Wii. Simple activities such as throwing a ball, catching a ball, and hitting a baseball do wonders for motor skills.
7. Creates self pride - When our kids got their jerseys with their own name on the back, the smile on their face was unforgettable. They really felt important and it created confidence.
6. Teaches kids that bullying is unacceptable - In both football and baseball this season, there were a few cases of some of the "alpha players" trying to assert themselves at the expense of the younger/smaller players. Both coaching staffs immediately addressed this with both the kids and the parents and the problem went away. Bullying is a terrible problem in schools and the more kids that can be turned off this path at an early age, the better.
5. Coaches are more like teachers than parents are. - As much as we try, we always see our children in a different light as an outsider....and that's a good thing. Coaches, like teachers tend to treat the kids equally and hold them all accountable for their actions and responsibilities.
4. Kids are learning Math and don't even realize it! - For all of you former football players out there, you'll likely remember that each "hole" (gap between lineman) is assigned a number telling the running back where to run the ball and the rest of the team how to block a play. As the kids learned this, I watched several kindergarten level students now able to count by 2's as that is the way the football numbering system works. Also, when coaches teach defensive players to run at an angle where the player with the ball is going to be, not where he is at....kids are getting introduced to geometry. As per my earlier blog entry...physics is everywhere as well!
3. Respecting elders - Talking back and yelling at coaches and other parents is not tolerated in most team sport environments and at the young ages of the players, this tends to stick with them away from the game field.
2. Teamwork - Team sports are a great way to teach kids how to work together for a common goal. Specifically, our kid's football coach requires all kids to run their laps as a group (emphasizing that this is not a race, but rather teaching them to do things together) and has them chant and do their warmups together as a group.
1. Exercise - Above all else, in the video game/tv dominated world we live in, I'm elated watching my kids get a couple hours of outside activity including cardio work, stretching, fun games, agility tasks, etc. Remember when we used to spend every summer day outside? This is a great way to show our kids what was great about our childhood and keep them in shape at the same time.
I'd love to hear others stories and reasons for or against team sports!

Physics of Sports
As a lifelong sports fan, I've always been interested in the science behind the sport. Relating physics to sports is a great way to peak the interest of students who love sports, but don't enjoy Physics as much as they could. I've found a few links that explain the science behind sports that I've enjoyed quite a bit and I think you might too:
Physics of Football:

Physics of Volleyball:
http://www.real-world-physics-problems.com/physics-of-volleyball.html
Physics of Soccer:
http://www.soccerballworld.com/Physics.htm
Enjoy! Using sports to teach children about science can be rewarding for all involved. After football practice yesterday, my kids received a geometry lesson (teaching angles of pursuit) and they were all ears and enthusiastic!
Have a great summer!

Price increases mid year?
Perhaps I'm a bit accustomed to working together with our valued distributors as opposed to working purely for the short term profit, but how can manufacturer's and importers see fit to increase prices in the middle of the year knowing full well that most of their customers print a catalog that is good for the entire year?
Are there really that many unforeseen cost increases? Was I the only one who saw that the economy is down? Was I the only one who saw that the dollar is weak?
I can surely understand that its not just some manufacturers causing problems. We've received our share of extremely demanding and ridiculous vendor agreements. My concern is that the continuous looking out for oneself versus working together for common success is going to have an immediate and long lasting impact on our industry.
Remember when relationships meant something in our business? I sure do. I'd like to see that come back. We pride ourselves at Fischer Technical that we, along with our principals, work with this in mind. Do you need a special service along with your order or have an "out of left field" request? Please ask us, the worst we can do is keep you in the same position that you were already in. Our way of business is to treat our distributors with the respect they deserve and we'll do all we can to meet any special requests. This is how small, family businesses have been successful over the years.
What actions do your vendors/distributors take that bother you? These are the ones that bother me the most:
1. Answer the phone please. - I'm not calling to sell you health insurance, I'm calling you to say hello, share with you a new product that others in the industry are profiting from, ask for your advice, share industry news, etc. Are we too big for phones these days?
2. Please reply to your email! - See #1
3. Please write down, use your computer calendar, etc our appointments. - Its frustrating when I've set an appointment, confirmed it a day or two before and show up at one of our distributors to find an empty office or to learn that they simply forgot about the meeting. I assure you, I've put a great deal of effort in my preparations and have spent hundreds or thousands of dollars to come see you. Its in both of our best interests for us both to be prepared.
4. Remember that I've taken an airplane to see you and likely have several appointments that day. - Ive been in situations where the person I'm meeting with decided to take a long/late lunch or asked for last minute rescheduling.
5. Please keep your word. - When I make a promise to put together a presentation for you or complete market research, I do everything in my power to complete the task to a "T". I'd rather hear an "I'm not interested" than for someone to put me to work on some extensive research just to transition the conversation/meeting.
6. Please do not demand to receive "The lowest price you offer". - This is most applicable when a vendor purchases a small fraction of a specific item and demands to receive the same price as someone who purchases 25x more. I always will offer you the best price I can and I value all of my distributors equally.
7. Give me a chance to make it right. - Murphy's law is always alive and well. Shipments can be damaged, storms can knock out our phone lines, we may even ship the order incorrectly on a very rare occasion. I assure you, it was not meant as a practical joke and we receive no joy in causing grief. When given the chance, good business people will always do what they can to right a wrong.
8. Please treat vendor - distributor relationships as a partnership. - The end goal for a business relationship is to make it profitable and fulfilling for both of us. Pushing one or the other around does not make it feel like a partnership and is not healthy for a solid long lasting business relationship.
By going back to the way small businesses became successful, vendor/dealer relations can improve and likely result in increased profits for all parties involved.
Have a great day!

Why so many Pipette Fillers?
Pipette fillers do a simple job. They draw samples into various types/sizes pipettes and dispense the samples into another location. That being said, I get asked all the time, why does Fischer Technical Company have twelve different pipette fillers on their product list? Let's take a look at them and see why!
Standard Three Valve Natural Rubber Pipettes -
These represent our best selling pipette fillers. They are made from natural rubber with three ball style valves plus a blowout valve. This is the classic model that has been used in laboratories for more years than most of us have been alive. They are available in four colors (Red, Black, Green, and Blue). Most laboratory technicians prefer the Red or Black models as these have been in the marketplace the longest. It's wise to use multiple colors if the pipettes are being used to draw different samples, particularly those that would react with each other. When used properly, no part of the sample should come in contact with the bulb itself. These bulbs are recommended for pipetting most solutions/samples. The easy to use three valve design requires two hands to operate. Item numbers are: RED-001, BLK-001, GRN-001, and BLU-001.
Multi-colored Natural Rubber Pipette filler - These pipette fillers share the same design and recommended applications as the standard three valve natural rubber pipette fillers with one obvious difference. Laboratory technicians, like many specialized professionals, often have unique and creative personalities. Why shouldn't their equipment reflect that? Many use colors that match their alma matter or favorite sports team. These bulbs are available in four different color combinations and have a "tye dye" appearance. Item number is MULTIPIP.
FLIP Style Natural Rubber Pipette Fillers - These pipette fillers are recommended for the same applications as the other natural rubber bulbs but have one significant design change. Instead of a manual valve at the top, which is used to remove the air from the bulb before drawing liquid, the patented "FLIP" model has an automatic valve at the top allowing for users to operate a pipette with one hand. This valve also can be removed to clean out the bulb if contaminants happen to find their way into the bulb. This version is new to the market in the past 20 years or so, ergo not as widely used, but the technology is more advanced than on the standard bulb. Note: Fischer Technical Company is the only wholesale distributor authorized to sell these in the US and we offer them through a variety of distributors. Contact me if you need to find an authorized dealer at JGura@fischertech.com. These are available in Red, Black, Blue, Green, and Yellow. Item numbers are FLIP-001, FLIP-002, FLIP-003, FLIP-004, and FLIP-005.
Silicone Three Valve Pipette Fillers - We also offer Red and Black pipette fillers, designed similar to our standard three valve pipette fillers, made with silicone rubber as opposed to natural rubber. These bulbs are ideal for pipetting solutions which react with natural rubber, either via direct contact with the liquid or from the fumes. We do not recommend using these, or any of our bulbs, in applications where the solution will come in direct contact with the pipette filler. These are also available from our wide network of authorized dealers. The item numbers are SILBLK-001 and SILRED-001.
All of our pipette bulbs can draw up to 50ml of liquid and can be used with pipettes up to 100ml. Note, for pipettes larger than 50ml, users are required to draw the liquid twice due to the 50ml capacity.
I hope this information is helpful in helping you choose the proper pipette filler for your application. Please do not hesitate to contact me with any questions at JGura@fischertech.com
Happy Pipetting!

Item numbers are FLIP-001, FLIP-002, FLIP-003, FLIP-004, and FLIP-005.
Silicone Three Valve Pipette Fillers - We also offer Red and Black pipette fillers, designed similar to our standard three valve pipette fillers, made with silicone rubber as opposed to natural rubber. These bulbs are ideal for pipetting solutions which react with natural rubber, either via direct contact with the liquid or from the fumes. We do not recommend using these, or any of our bulbs, in applications where the solution will come in direct contact with the pipette filler. These are also available from our wide network of authorized dealers. The item numbers are SILBLK-001 and SILRED-001.All of our pipette bulbs can draw up to 50ml of liquid and can be used with pipettes up to 100ml. Note, for pipettes larger than 50ml, users are required to draw the liquid twice due to the 50ml capacity.
I hope this information is helpful in helping you choose the proper pipette filler for your application. Please do not hesitate to contact me with any questions at JGura@fischertech.com
Happy Pipetting!
