Introduction: Tennis Ball Canon/mortar
In this project, we constructed a tennis ball mortar cannon. We made some minor modifications to improve the quality of the cannon.
One of these modifications was making the first hole smaller so more energy from the lighter fluid is focused all onto the tennis ball.
1. You will need to find 3 Pringles cans. You must cut a hole at the bottom of one, small enough to hold a tennis ball.
You will need to cut a much larger hole in another can big enough for a tennis ball to go through. Leave the third alone. Discard the lids.
2. Stack them in this order: Can with no holes, can with small hole, can with big hole on top.
4. After layering with duct tape, make a small hole at the bottom of the bottom tube. This is where you will put in the lighter fluid, and later, the lighter. We added handles to hold when we launch it.
We have a be nice policy.
Please be positive and constructive.
