Step 3Put it together
Lay a piece of wood on one of the tabs. Then fold the rag over the wood and wrap the duct tape around it so the wood is stuck inside. Repeat for the opposite side and the other piece of wood.
Next, lay out the surgical tubing so that it runs over one of the other two tabs. Then curve it 180 degrees so that it runs down the other side of the rag. Once again, tape the rag over the tubing. Make sure you don't actually tape the tubing so that the pocket can slide freely up and down the tubing. Tape all of the corners and seams to reinforce them. You can not have to much tape on this project.

Ahha we made the same thing, at least ahha i guess better quality since it was for our school physics project, it fitted in a 1 meter cube and launched at least 40 meters easily, i think the design of the "wildsling"'s pocket was nice and we made it it worked very well. Does your ductape thing have to be release at the same time to shoot straight? ahha
