Transcript: What Is Weightlessness?

RACHEL: This phenom was sent in by David G. of Columbus, Ohio. Here's a cup with two holes in it. See how the water is pouring out of the holes?

KALEIGH: If we drop the cup what do you think will happen to the water coming out of the holes while the cup falls? Will the water come out of the holes faster? Will the water come out of the top of the cup? Or will the water stop pouring out of the cup altogether? Make a prediction. Okay, let's see if you were right.

RACHEL: Okay, here we go.

KALEIGH: Whoa!

RACHEL: Did you see how the water stopped pouring out of the holes? Was your prediction right? I'll explain. When I hold the cup the water pours out of the holes because of gravity. But when the water and the cup fall together, the water doesn't need to pour out of the holes to get down. It just falls with the cup. This is probably hard to see on TV, so try it at home.
