This is one of my school projects and we had to publish it on instructables. I hope you like it.
Step 1: What You Will Need
any small toy,
coloured paper and hot glue,
some kind of bottle cap or cup thing.
Step 2: Step 2
Get a box that you think will be good enough for this project.
Step 3: Step 3
Get any coloured paper and decorate the box by stick the paper on with any pattern. This is what I did.
Step 4: Step 4
Poke holes on the sides of the box for the pop sticks to go through.
Step 5: Step 5
Stick four pop sticks together.
Cut 3 or 4 pieces of cardboard into this shape to make a cam, stick them together and poke a hole through them.
Step 7: Step 7
Put the pop sticks through the holes in the box and put the popsticks through the cam.
Step 8: Step 8
Put another stick on the cam and poke a hole in the box where you want your small toy to go.
Step 9: Step 9
Hot glue the stick to the small toy. Then you can start decorating the surroundings of the small toy.
Step 10: Step 10
When you rotate the pop stick axle, the cam moves, making the toy jump up and down. Enjoy your simple machine!
