Algodoo

It might be a little strange looking when it fires, but it fires further and faster than my compound bow. Unlike my compound bow, this bow doesn't use springs. It only uses hinges for firing the arrow (and not motors).
Pull the arrow in and back like my compound bow, but only pull the arrows back about 4/5 of the way, or it'll go through the bowstring (I'll change the arrow length later).
Have fun, and remember to compare it to my compound bow sometime!
