AutoSTEM Catapult How To Make The Catapult

That's more will take 9 of the sticks, join it together with elastic band . You can use glue, elastic band is easier to put on the past. The shortest time. Next to make the holes in the top stick, the arm is going to help, and the bottle lid. It's going to be called the bucket. Let's then thread the split pin through these pieces. First of all, pocket. Then the arm finding the throwing gun. It's coming a little bit fiddly. Which pushes through, pull down the two sides of the split pin and get that nice and tight. You can use a hot melt glue gun for this. Once you've done that, you take the remaining two sticks, join to roll up the firing to the bucket. The same way I should do the first ones. Now we're ready to start the fulcrum which is the roll in my sticks and push that between one to two at the bottom and one at the top. Now you're ready to go. Pull down the arm and off the volunteer case. The news pencil to do the same job.
