What you need:
- 10 pencils
- at least 14 rubber bands
- strong string
- bottle cap
- something to make a hole in the bottle cap
Also please remember to vote for me in the office supplies contest.
Do what the picture shows.
This is the the next step. also use more than one rubber band if you want to make it stronger.
Make a square.
Make a slanted square on top.
Put this on.
Put the other pencil on and tie the string on the bottom.
Cut one of the rubber bands.
Tie the rubber band around the two front pencils.
Put the last pencil through the string.
Wind the pencil up in the string
Push the pencil up through the string and place it behind the rubber band.
Make a hole in the bottle cap big enough so the pencil can fit in.
Now push the pencil into the bottle cap. Now your finished! Hope you have fun! You can also slide the string back and forth along the two side pencils to change the angle of the catapult, and the farther you wind the pencil in the string the farther it will go!
