What Makes playing fetch with your dog much more fun?
• A catapult will be the solution for this problem because everybody loves launching a tennis ball.
• Or some other kind of machine that will launch it like an airsoft canon.
Why did I choose this project?
• I have two dogs and I atleast have to play fetch with them twice a day.
• Somedays my arm is soar from baseball
• The dogs never get tired and so I can make them tired this way
• My brothers and sister would want to play fetch too.
what I enjoyed most
• Working with my Grandpa
• Learning how to use different tools
• Launching the tennis ball for my dogs
How to launch the catapult.
• Get a normal sized tennis ball
• put it in the ball in the yellow bowl
• pull back on the hand of the catapult
• make sure the dogs are not in the way
• release the hand.
• the ball should go a distance of about 120 ft.
problems encountered
• We got the measurements of an angle for the 2x4 piece of wood wrong three time.
My ipad got hit by the hand of the catapult when I was taking a video.
What I learned from this activity
• Launching a catapult is a lot of fun
• The dogs got tired much quicker
• Surgical tubing is very strong
• My brothas n sistas loved it too
Things I would do differently next time
• make my catapult much smaller
• Add more weight to the base of the catapult so it doesn't rise off the ground when launched
• make it launch farther because I think it would be more fun
The most difficult/challenging aspect of my project.
• building the catapult one day at a time.
I wanted to just get it built so can start on my
