I will see if a homemade slingshot or a store bought slingshot will sling a rock the farthest. I will test this out with different objects, too. In my mom's room, she has these rubbery things that remind me of slingshots and when she first brought them, I wanted to make a slingshot of my own. Now, in this experiment, I will get to do just that. With the results of my experiment, people can decide if they want to buy a slingshot, or make their own.
