You can also use those little Pringles boxes. Fisrt off, make the balls heavier than the regular balls. Have a smoke bomb in the box somewhere too. Poke a hole in the lid and the bottom of the canister. Have the wick of the bomb comming out of the bottom of the canister. Pump air into the top, and tape the hole up. Light the bomb and enjoy the show!!!
i disagree with you entirely. Maybe you should follow up with the topic from more than one perspective. Just think of the scientists' reactions when they get a lab on the moon! I'm pretty sure they'd be happy.
