Toilet Paper Engine. Simple, easy to make, and fun, this model engine is made from cheap easy-to-find materials.
It runs on compressed air supplied by your lungs as you blow the piston down and then suck it back up! It demonstrates principles of motion and engine operation, and allows students to learn the main parts of any engine: Crankcase, Crankshaft, Connecting Rod, Piston, Cylinder, and Flywheels. I can't take credit for "inventing" this cool project but I've adapted this to make it a lot easier to build, and it can be done very quickly. This is an activity I do with my 7th and 8th grade students in a Small Engines Repair class, but it could be used for many other activities like drafting, measuring, studying the laws of motion, or even a history project, as it closely remembers an old hit and miss engine.
