Simple Machine in Toy

First I make plan.

Then I find a box that I thing i can make machine with that.

I want to have three stick working in my machine then thing about simple machine " Ha I found one that is gear" I said. I make three gear connect to three stick.

Next I make a cam in my box to make it like a machine.

Next I make a lever because it easy for my machine to be working at all.

Next I color everything. You can draw and cut the picture that you want.
