Loop the Loop

Nice piece of equipment.

Loop the Loop

This is a great item for our lab. All the kids love it. I have to hide the balls or they will be on this all day. They use other balls, too, like marbles and the like, when they can't get the real thing.

Good product

Good solid product. Used it for a lab on potential energy and kinetic energy of rolling vs. sliding objects as well as a discussion of the work of friction. Would be even better if it included a hollow ball vs. solid ball.
