Ever wonder what to do with those old science fair display boards? Why not make something that SHOOTS STUFF? What middle school kid doesn't love that!!
This is not powerful enough to hurt someone, but if it does, DON"T BLAME ME!!
Step 1: Needed
What you need:
-2 small sticks
-1 bigger stick
-Folding display board
-Big stick (shown in later pic)
Step 2: Cuttting
The Pictures show where to cut!
Use pencil for holes!
Step 3: Elastics
If you are using small elastics, you have to string them together like in the picture. I folded the long strand in 4ths and put the ends through the holes, using the small sticks to hold them.
Step 4: Structure
You are going to have to use a big stick put down the middle of the catapult arm to hold it stiff. use a lot of tape. I only had scotch tape, but I recommend duct tape.
Step 5: Top of Catapult
You need a bucket to hold ammo. fold the sides and tape a scrap to the bottom.
Step 6: Angle Restrictor
This is a fancy term for a stick placed so it won't go to far.
Step 7: Done!
Get some ammo, pull back, and FIRE!!!!
