My catapult By: Marshall Lockyer
My design • I made my own design after trying other designs. • I made this one as the other design would stop the bar before it would release the ball
Why I chose this project • I chose this project because I wanted something that was fun, challenging but not to difficult.
Some challenges • Getting the right design • Not giving it to my dad so he could do it for me. • Finding a way to make it more powerful
Way I solved these challenges • I tinkered with the design and made adjustments • Not asking for unnecessary help • Adding things to make it go farther.
How I came up with the design • I came up with the design when I decided I wanted to make my own unique design that was not one I found on the internet so that is why it looks odd and looks like it wont go far.
Unfortunate disasters • Some bad things that happened were catapults breaking. ( I made 3 after the first one broke and the second one would not shoot) • The cup that held the ball broke yesterday • Not being able to put a video of it shooting on this power point.
What it shoots • It can shoot multiple things like tennis balls, golf balls if you really wanted to, and other small items
How it works • It works when I pull back on the thing that will release the item, then I let go and most of the time it will work
What was the goal of the project • The goal of the project was to design a catapult that would shoot a tennis ball and test more than 1 design as I tested three.
How long it took me to make • It took me about 4 hours to make it. It took this time because I was experimenting with the design. I also have to add 2 more hours on to that due to repairs. So it took about 5 hours.
Video of shooting. • I will put in this video because I can not bring it to school because I take the bus. (on the wiki)
