Hello, are you a kid that just wants to have fun on your last summer day? You have come to the write place. Now this is an experment so you will need some supplies. First get a tennis ball (or a ping pong ball is better) and a basketball drop both on each other from about your shoulders. Watch the tennis ball fly to Mars as the basketball stays still on the floor. I have tried this experiment many times but the best one was when i droped a bouncy ball on a golfball. It was amazing distance upwards. This is just a really fun way to just hang out before school starts again. Please say you liked it… I know i did trying it out on all these differnt objects have fun Bye.
