Intro: Knex Rocket That Really Launches
This is a Knex rocket that actually launches using 4 large rubber bands. It is very simple and uses few pieces. It flies about 20 ft. Watch this video for proof. Please rate. Check out my new cannon.

Step 1: Rocket
This is the projectile shot out of the base.
Step 2: Base
The Rocket shoots out of this.
Step 3: Adding the Rubber Bands
You place each of the rubber bands around the white peg at the top. Then you add the rocket. Finally you pull down the rocket on to the rod and release it. Watch this cool video to see the launch.
