We were staying at my grandparents and my brother found a LEGO set that one of my cousins had left there. (Because if there is LEGO, he will find it.) It is a LEGO Technic set. The instruction booklet had a bunch of cool moving contraptions like a blender or an extending claw! The gadget I'm about to show you is called the "Wall Rocket Launcher." You are about to find out why.

| This is a souped up version, designed for a rider. |
Here are the basic components if you wish to make your own. Plus, it's cool to see how this thing works.
First off, you'll need several LEGO Technic pieces. If you don't have any, you really can't make this. In addition to the LEGO pieces, you'll need two thin rubber bands.
Here's a view of it with all the roof pieces taken off. Look at the pole with the red thing on the end sticking out. You push that against a wall, release it and the car shoots forward.
Bottom view.
The rubber band it pulled through the thing on the end next to the red piece (Called an axle connector). The second rubber band is wrapped around the pole as many times as you can wrap it. I'm not sure why, to act as some kind of buffer maybe. On the right are two 1x4 bricks with holes (Or called Technic bricks). The pole goes through the hole in the middle and the rubber band is threaded throughout the hole on either side of the pole.
The rubber band come out of the holes...
And wraps around to the bottom. Next to the axle holding the wheels are two technic connectors. The rubber band is looped around those.
To work it, push the pole up against the wall.
Push it as far back as it will go...
Then release quickly. It will shoot off.
Technic pieces are great for moving things. What cool contraptions can you build with them?
