Algodoo

A very simple, stable, reliable, and un-explosive bow. There are no springs, no motors, no nothin' but the limbs and bowstring (well, rope I guess). What'cha see is what'cha get. The only thing that you can't see is the arrow stabilizer, which isn't very strong anyway. It's at the back of each arrow.

Instructions (as if you need them):

Grab an arrow.
Put it in between the two gray boxes on the bow.
Pull the arrow back until the arrowhead touches the limbs.
Release the arrow.

P.S. It's called a chain bow because it's not a long bow, a recurve bow, a crossbow, a compound bow...it's not any bow anybody's made a name for. So I named it Chainbow, because it uses algodoo chains (boxes/circles axled together).

UPDATE:

A new arrow called the Tri-Arrow has just been released!
All it is is an arrow, and an arrow, and an arrow, all stuck together!

NOTICE: The arrows that are loaded in the bows may not work, so if you have difficulty with the bows backfiring or exploding, be sure to carefully nock a different arrow, and gently pull back until the arrowhead touches the bow.
