This is my first instructable and its a Pencil Shooter that is launched from a Crayola Marker tube. It is pretty strong. It can break the wall of a Diet Coke can.

Step 1: Materials Need

The materials you will need are probaly all in your house right now.

1. A fat Crayola Marker
2. A Wooden Pencil
3. A thicker Ruberband
4. A razor blade

Step 2: De Assemble

Now you are going to take apart the marker. All you need is the Big Tube. Once your done with that you might want to cut off the skinny part at the end.

Step 3: Cutting

This is where your going to need your Razor Blade. First you will cut 2 little divits on the top of crayola marker. This is where the rubber band will stay. Then in the middle or maybe a little lower than the middle cut 3 or 4 pop out things so the rubber band will stay there and wont fly up.

Srry these were the worst pictures. :(

Step 4: Rubber Band Settup

First you will take your rubber band and loop it so theres 2 loops. Put one in the 2 divits you cut at the top and the other loop under the pop out things so its tight. If its not tight loop it again so it becomes tighter. This step is the hardest to explain.

Step 5: Firing and Warnings

I think you know how to fire it. You put the pencil in eraser first and push it up till you can grab it with the rubber band. Then pull back and realease and it will fly. Be warned this could poke someones eye out so dont hit any living thing with it because it will hurt them.
