Step 1: : )

Hi everyone today I am going to show you how to make an office supply catapult. What you will need is

1 hammer
1 pair of scissors
Tape
1 screw or nail I am using a screw because they are thicker
2 pill bottles
1 rubber band
A piece of cardboard 11"L x 9"W
2 pens any type any size
1 spoon
And 3 paper clips

Step 2: Punching the Holes

First you want to take the hammer and hammer the screw or nail into the middle of both the pill bottles. I found that if you idea. Screw its easier because you only have to puncture the bottle, and you can the twist the screw to make the hole bigger. Depending on what kind of pill bottle you use this step might take longer.

Step 3: Threading the Band

Cut the rubber band once and thread one side through one pill bottle. Then attach the rubber band to the paper clip like so. Then pull tight. Then do the same thing with the other pill bottle, and other side of the band. You should now have something like picture number 3.

Step 4: Taping the Pen

You need to next tape the pen to the bottom of the bottle like so.

Step 5: Taping the Spoon

Next you need to tape the spoon in the middle of the rubber band.

Step 6: Finishing

The extra spoon and paper clip are for the launch you will want to hot glue the 2 towers to the cardboard. It works and is awesome enjoy!!!
