A Boat Tailed Waggon

Fish and Lilypad are on the loose trying to get a good grade on a school project. But these two aren't book worms, so this is likely to be physical physics.

Proving the force of gravity is difficult if you are a young filly. The only logical thing to do is to go out and find a really steep hill and roll down it in a home made cart. Luckily for Fish and Lilypad their hooves-on approach to physics doesn't involve any permanent damage.
