Introduction: Rock Shooter
This is my first instructable so it might not be that good.
This is a very simple rock shooter heres how to make it:
What you will need;
-A fairly long piece of cardboard tubing
-some thin cardboard
WARING: DO DOT SHOOT AT ANY ANIMAL OR HUMAN MAY RESULT IN INJURY!!
Step 1: Stringing the Elastics and Installing Them
To connect the elastics place one elastic over the other one (see picture) then pull the one on the bottom so it goes around the other one and then pulling it thru itself. It sounds hard but its really easy. Then attatch annother on to the chain with the same knot. Then cut one of the end elastics like in the second pic. after that tape it to the end of the tube like in the third pic.
Step 2: Extending the String
Tie the string thats about the length of the tube to the end of the elastic chain and then tie a paperclip to the end of the string. Drop the paper clip down the tube so you can grab it at the other end. Pull it a few times to make sure its strong enough.
Step 3: Adding the Firing Mechanism
Now drill a small hole in the cork. If your cork fits snuggly in the tube you will not have to do this but if it dosent tape some thin cardboard around the cork. Now feed the string through the cork until you reach the elastics, then jam a paperclip into the hole along side the string to keep it in place.
Step 4: FIRE!!
Make sure no one is in the way then drop a rock down the barrel aim it at a fairly high angle and pull back the string until you can see the end of the cork and then let go to send the rock flying!!!!!!!!:)
We have a be nice policy.
Please be positive and constructive.
