Sue loves drawing with a Spirograph. But her friend slime
Sam is too bored to wait for his turn. So he steals all the Spirograph parts
from Sue. It's a good thing that Sue knows how to make crafts from cardboard.
So she simply builds a drawing machine from scratch! This machine doesn't need
electricity. To make it, you'll need thick cardboard, bearings, wooden rulers,
bolts and nuts, wooden sticks and hot glue to put it all together. The main
mechanism of this machine are three large gears. They are placed on the base in
certain order and then an arm made of wooden rulers is attached to them.
