I built a small pocket launch pad, because being bored can get boring.
Step 1: Trace, Cut, and Place
Trace the tin onto the lined side of the card, then cut it out and place it in the tin. Be sure to flatten down the sides using the keyring.
Step 2: Draw the Launch Pad Out
Using whatever pen or marker you like, draw a 1 1/2 inch circlein the middle of the card at the bottom of the tin.
Step 3: Build the Rocket
Take your bullet shell, and put it in the clipper, then put the keyring over the top.
Step 4: How It Works
Push the clip down over the rocket (Watch out for it hitting you in the face)
