Now for the good stuff :)
This is a fun and easy (and cheap) little toy that I invented the other day. It's very strong and shoots very far.
What you'll need:
1 Office Depot Ballpoint pen - very cheap -- 1 dozen for $0.89
(this might work with other pens, but I haven't tried)
1 Rubber band of medium length
Step 1: Making the Barrel
This is a very easy step, if you can't figure it out, you LOSE. Please try again.
Step 2: Placing the Rubberband
You want to make sure that the rubberband lies only about an inch and a half past the firing end when it is fully stretched.
*Note* The firing end is the end opposite the side you write with.
It's the one with the wider hole.
Step 3: Securing the Rubberband
How much string you use and where you place it will affect how your rubberband stretches.
Tie the string off at the end so it won't come loose.
Step 4: Loading the Ammo
Insert it into the wide hole of the barrel so that the pointy end goes in last.
Let it slide all the way to the bottom.
If you are using an Office Depot pen, the ink cartridge will fit in there very nicely.
Step 5: Firing
*Note* If you pull too tight, the ink cartridge might:
a) break within the pen, thus making a big mess
b) fly too hard and explode as it hits a rigid object, thus making a big mess
If you made this properly, it should fire around 30 feet at least.
Make modifications to your rubberband as needed.
Have fun and be safe :) (OR ELSE!)
