Trash Catapult

Why you should buy it
You should buy it because it would make your life better by throwing the trash away for you! Are you tired of picking up trash all the time? Well then there would not be a good reason not to get the Trash catapult.
Another reason to get it would be to help the side walks that are full of trash.
Materials
Most of the materials are very basic. They are materials that you can find around the house like string, a box, a rock, a car ramp, a piece of trash, lever, paper towel roll, tape, box of dominoes. As you see the materials are very basic. You could just walk around in the house and find these materials.
How does it work
This simple machine is very easy to run. The first step is to put the box of dominoes over the piece of string which is holding down the rock. Second, step is cut the string. Third, String lets rock go. Forth, rock hits lever. Fifth, throws away trash.
What does it look like
The simple machine has flashy colors. It is a household size it is also 1 and an half foot tall, and about foot long.
Our most reasonable price is
$25.95 plus tax
I like your project. It’s a pretty different idea! Your description is well done, except for a few mistakes. How did you think of it? I don’t think I would ever have thought of that unless I treid for a while. Overall, I liked your project. Ty H.
