Resources mentioned in Chapter 13 – Make Your Own Maker Day
Marble runs and ramps – The Tinkering Studio site for Marble Machines. These large scale machines are built for crowds, but the resources will be helpful for any size build.
Scribbling machines – Easy to build robots using scrap materials with pens for legs and a small off-center motor. The vibrating motor causes the robot to dance around and scribble on a large sheet of paper.
Wind Tubes – Easy to make large upright tubes with a fan at the bottom. Makers can build “stuff that floats” out of recycled materials, put their creations in the tube and watch them fly up to the sky!
