Algodoo

A compound bow that has Ultra Nock arrows. Ultra Nock arrows will stay on the bow string when you nock them, but when you shoot them they completely free themselves from the bowstring.

This compound bow doesn't use pulleys or cams or anything, so it gets harder to draw the further you pull instead of the other way around.

The arrow on the right behind the bow is a standard arrow, and the stack of arrows are all Ultra Nocks.

Ultra Nock Instructions:

Grab an arrow with the drag tool, preferably with a low drag tool strength (I find 1,000,000 is a good drag setting for me).

Drag the back of the arrow through the arrow guide all the way back to the bow string.

Hit the back of the arrow against the bow string fairly hard, and check to see if the arrow secured itself on the bow string. If it's not on, try again.

Once the arrow is set in place, drag the bowstring back until the arrow head is almost to the handle.

Release, and the bow and arrow should do the rest for you.

Sometimes the arrow will go through the bow string, but as long as you're careful, you should be fine (One reason to have a low drag strength).

Well, that's about all there is to tell, so have fun with it, and please remember to rate and comment.
