Instructables
Many a times I have been wanting to build something dangerous from something not so dangerous. I went through a “pen gun” phase where I went crazy about building a pen gun. I was somewhat successful but not perfect. I needed a weapon that would bother the guy next to me but not something that would get me in trouble. I came up with this...the 5 minute binder clip catapult. If you are interested, read below.

Step 1: DISCLAIMER

DISCLAIMER:

I, (NAME GOES HERE), HEREBY GRANT MYSELF TO USE SUCH DANGEROUS OF A WEAPON. I PROMISE TO USE THIS IN THE NAME OF GOOD AND TO BOTHER PEOPLE...NOT TO KILL. IF HOWEVER ANY INJURIES TAKE PLACE I MAY NOT HOLD  blinkyblinky RESPONSIBLE FOR ANY CHARGES. BUILDING A DEVICE AS LETHAL AS THIS IS OF YOUR OWN CHOICE AND SO, IF I AM CHARGED WITH FIRST DEGREE MURDER, I HAVE NO RIGHT TO BLAME blinkyblinky FOR ANY CHARGES PRESSED UPON MYSELF.


Now, with that out of the way, let us begin.

Step 2: Get Your Materials

You will need:
1 oversized binder clip (use the biggest you can find.)
A handful of assorted rubber bands
1 Plastic Spoon
Someone to Bother (victim)

Step 3: Attachments

First attach securely to the binder clip, the spoon via rubber band. on one end of the clip. (Refer to the first picture.)

Attach a rubber band via loop to the other "arm"(Refer to picture two.)

Repeat the previous step two to three times.

Then, pull over the rubber bands in the gap between the spoon and the arm. (Refer to picture two.)

Assembled and ready for firing!

I find that just putting some tape around handle makes a nice cup for catapulting. That way, you're using all the power of the binder clip for shooting. And you don't have to bother with a spoon and all those rubber bands.

I like rubber bands. I like spoons. Plus this thing has super power when firing. I use lever technology and so it is fine the way it is...

I like your suggestion though. However the way it is is fine to me.
