Constant Velocity Car (Tumble Buggy)

I have used these cars for several years now on my one directional motion labs. They work great, and have had good results. G. Busse Minnesota

Constant Velocity Success

I had no problems with shipping. The cars were neatly packed. No issues with damage. My 11th grade Physics class loved working with them.

Love the toy cars. Also please Keep carrying them in two colors. I use the blue ones with two batteries and the red ones with one battery so that they run slower. These were great for the constant velocity lab that I do to start the year. The only improvement they could make is having them go in a straight line more consistently. I find that they curve really easily and don’t always go in a straight line.
