So yeah I'm going to teach you how to make the hardest ammo ever for your rubberband slingshot. This hurts, so be careful. And bear with me please, this is my first instructable.

Step 1: Materials

Materials:
Regular exercise book,
Rubberband,
Hands,
A working brain.
First, get a regular size exercise book. But, the bigger the better. Some types of paper wouldn't work, so it's better not to use counter books.

Step 2: Cut...

Tear about an inch off the edge of the length of the page.

Step 3: Roll...

Roll it up till about half the length... then flatten it.

Step 4: Folding...

Then fold the flat part in half... as many times as possible. I managed two, which is usually the max.

Step 5: More Rolling...

Then roll up the rest of it.

Step 6: Ready the Cannons And...

Now fold it in half... It might be really hard so you can use a tabletop to help... Aand your'e done!

Step 7: SHOOT!

Just added this step in case someone stumbled onto this without knowing how to use it. Just use your fingers as a slingshot. This can be really painful, so be careful!

EDIT: I made this instructable a few years ago as a ( still pretty immature ) 14 year old, so forgive me for the terrible pics and confusing language XD
