A pocket-sized pen launcher made out of a Tic-Tac box. Great for office wars.

WARNING: THIS CAN PIERCE ITEMS AND SKIN EASILY. I WON'T BE BLAMED FOR MAYHEM YOU CAUSED.

Items needed:
_ 1 Tic-Tac box of any flavor (preferably 18 grams)
_ White paper
_ 1 Paper clip
_ 1 rubber-band
_ Knife
_ Color Pencil (any color of you're taste)
_ Ink and point part of a pen
_ Ruler

Step 1: Drill Da Box!

Make a hole at the back of the Tic-Tac box with the help of the knife. the hole should be at about 2.5 cm from the top, which isn't where the cap is. Make it large enough foer pens to go through.

Step 2: Ze Rubber'z Location Shaping

Carve two small lines to hold the rubber band at the very top of the cap, and two more at the middle of the hole at the back. Do not put the rubber band yet.

Step 3: Tapping, a Fun Activity :P Part 1

Take out double sided tape and single sided tape. We will TAPE things together. fun, ain't it?
First, cut 3 pieces of paper. Two of them should be 6.2 cm x 1.5 cm. the other should be 1.2 cm x 6.2. On one of the 6.2 cm x 1.5 cm, and using you're color pencil, draw lines of about 1 cm separating each other. Those lines will show the strength of the pull. tape the 6.2 cm x 1.5 cm on the top sides. Tape the one with lines on the left part if the cap isn't facing you. As usual, the top isn't where the cap is. The other one should be taped on the top.

Step 4: Tapping, a Fun Activity :P Part 2

This part is optional! It is for tapping the sight (which doesn't work at all).
But if you want to do it, then i won't stop you!
Take the clip, and bend the bottom part, which is opposite to both arches.
Then tape the small loop on top of the Tic-Tac box, with the big loop facing the cap.

Step 5: Fitting the Flying Band! Aka Rubber Band

Put the rubber band on the 4 holes you made earlier. DO NOT TAPE IT, cause you want to be able to readjust it later and replace it with new ones.

Step 6: AMMO, Your Friend or Enemy... You Choose!

This is the most dangerous item of the catapult, when shot! i tried on card board, it basically made huge holes on it! And the speed is incredible! Believe me!
Take the ink and point part of the pen (the rest is trash) and look at the back. Cut a line through the back so you can stabilize it on the rubber band.

Step 7: The Shooting

Open the cap of the Tic Tac box. Put the ammo in it and through the hole. Put the carved line present on the back of the ammo on the band. Stretch it and release hell!
