Toy Physics–Rollback Toy Challenge–Homemade Science with Bruce Yeany

The rollback toy idea is put to the test to see how far we can get it to travel when powered by just three rubber bands. It is a great example of changing potential mechanical energy into kinetic motion energy. Fine tuning and given a long and wide enough area, this roll back toy has the potential to go 200 feet or more. Another possible challenge for this toy might be to see how far it can roll away from a person, and then return back to the original position since that was the original idea for a rollback toy.
