How to make a ramp walker from pizza boxes

Science teacher Bruce Yeany demonstrates a ramp walker he made from a pizza box and some scrap cardboard.

Ramp walking toys have actually been around for quite a while, the first ones were metal elephants produced back in the 1800s. In the 1930 and '40s the popular material was plastic made that was made into Disney and other popular characters. Recently there has been a surge in wooden ramp walking toys. The wooden toys are very durable but require woodworking tools for making them. While less durable it is also possible to make these toys out of paper and cardboard. Here is an example of ramp walkers made out of used pizza boxes. In future videos. I will show additional ramp walkers made from recycled materials that are easy to build with simple hand tools.
