Intro: Binder Clip Catapult
Hello... this is my first instructable so it's not that impressive ;/
Btw I only have webcam for now. I made this when I was in history class with some friends of mine. We got caught many times with this, so be careful with it.
This mini catapult will take 5-10 minutes to create and you should have most of the materials.
STUFF TO GET:
- 1 Rubber Band
-1 Binder Clip
-Index card/cardboard (I used the index card)
- Tape(clear tape is fine)
Step 1: Preparing All the Stuff
Get the index card and fold it in half lengthwise. Then fold it into fifths(i had a small binder clip. This varies.). Tape that into place.
Step 2: Binder Clip
Put the clip onto the folded index card and close one of the metal parts down. Make sure the closed metal parts are hanging over the edge of the index card. If it doesn't, then trim it a little.
Step 3: Rubber Band Mechanism
This is the most confusing part. Take your rubber band and wrap it around the open part three times(or more). Then, loop it around the closed metal part once or twice, depending on how stretchy your rubber band is. Wrap the access rubber band on the open part until the clip is leaning downwards on its own.
Step 4: Final Steps!!
On the section that is leaning down(used to be upright), wrap small pieces of tape on the curved metal part to create a place to load ammo.
Step 5: DONE
Ammo can be any small objects. I use paper balls because those are the easiest to make.
To fire, you have to pull up the part with tape, hold your ammo on there, and release. If fired correctly, the projectile will go 3 to 4 feet.
Step 6: THANKS!
Thanks for reading my first Instructable and I hope you have fun with it.
