How to Make a Catapult Trap with Office Supplies

I love quick and simple projects that can be made from everyday items. With that thought in mind, I decided it would be fun to make a tiny catapult trap. This tutorial video was soon to follow:

You Will Need

1 Large Eraser
3 Paper Clips
1 Popsicle Stick
1 Spring (this could be from a broken electronic device in the battery compartment)
1 Chapstick Cap
Hot Glue
Strong Scissors
Pliers
String or Dental Floss for a Tripwire

Have fun! If you have questions, post below.

Nice. The eraser is a great aesthetic touch. :)

I might have to make one of these while proctoring finals. Now to steal some office supplies!

Wow- there is one of these in that DIY book I won a while ago made out of a mouse trap.

This is a need !!

Used this for a class I offer to 5th graders. Its very important that you get a soft spring. Hard spring will tend to bend the eraser. The trip wire is virtually impossible to make. I did not make 1 or two of these I mass produced 14 of these and i prototyped at home before the class. The eraser should be a pink eraser type. I went through the eraser with the clips and bent them underneath. I use over 10 different types of spring and came to the conclusion that this project needs a very soft/light spring, I can stress this enough.

that's a nice practice !!!

YES
