The previous video on the tennis ball cannon showed how it might demonstrate Newton's third law along with some measurements of the ball's muzzle velocity. Interestingly eno While the measured velocities showed a wide margin from one trial to the next we found it to still be a device that students found interesting. In this video I ran some additional tests that I thought might be interesting. There are more ideas that I had but still did not get to due to time constraints or limitations to being indoors.
Notes: Safety should always be the first concern. Wear protective eyewear and always have proper supervision.

1.The barrel length is limited to one can due to safety concerns.

2.There are fuels that are more powerful than lighter fluid but I use it since I am familiar with it and have used for many years.
