How to make a Minion Scribble Bot

Scribble Bots are a brilliant fun, mini engineering challenge offering lots of scope for investigations. Try changing the size or shape of the container, number of pens, number of batteries, size of propeller, make the propeller off centre or move the pens higher or lower up the container. Can you predict how each change will affect the way the scribble bot draws?
