Students Successfully Create a Mini Roller Coaster
These students tried to create a handmade rollercoaster for a school project. They joined some school furniture to create an elevated platform, protected by cardboard panels, that sloped down to the floor. One of them sat on a square drawer-like box, with wheels attached underneath.
The person sitting in the box gravitated towards the lower elevation, and slid down smoothly to the floor through the path, thus creating a successful rollercoaster project.
