Backyard Ballistics: Build Potato Cannons, Paper Match Rockets, Cincinnati Fire Kites, Tennis Ball Mortars, and More Dynamite Devices by William GurstelleOrdinary folks can construct 13 awesome ballistic devices in their garage or basement workshops using inexpensive household or hardware store materials and this step-by-step guide. Clear instructions, diagrams, and photographs show how to build projects ranging from the simple—a match-powered rocket—to the more complex—a scale-model, table-top catapult—to the offbeat—a tennis ball cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton. This book will be indispensable for the legions of backyard toy-rocket launchers and fireworks fanatics who wish every day was the fourth of July.

Lorrie Lynn October 22, Views. Junior Joey Knapp launches his tennis ball as senior Annabelle Warren and other physics students watch. On Thursday and Friday physics students competed in a tennis ball launching competition. They used homemade launchers to try to get as close to a target as possible. The first launch was towards a target about two meters away, while the second stood about six meters away. The students previously filled out collaboration tables to prove that their machinery would be up to par.
This is a catapult ala torsion style I built inspired from the video a contributor named schoondogs posted. His catapult looked simple enough so I thought I'd make a step-by-step with some improvements that's the American way right? The design is not pretty but it is very functional and that's really all a 5 year old cares about anyway. It took about three hours to build not counting the trips to Home Depot and does not include any difficult cuts all straight cuts or elaborate tools. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Cut the 2x4s into 14" and 30" lengths.
I am sure that a lot of you, at some point in your life, have built a catapult, either for a Physics class or something along those lines or for pure enjoyment. I currently need to built a catapult for an Honors Physics class over February vacation. The projectile has been predetermined as a standard tennis ball. My catapult must launch said tennis ball roughly half a football field 45 meters into a trash can. However, the catapult must be not greater in size than one cubic meter I have access to a bunch of tools and wood which I have decided to be the medium for my project.
