The Question

(Submitted January 01, 1998)

How could I model a black hole for a science project? I am in the third grade.

The Answer

If you can get hold of a sheet of rubber, or some other fabric that stretches. You can use that as an analogy of space: Put something heavy on it, that would be like a normal star. Roll a little marble around it.

Now make a hole in the sheet, and pull the edges of the hole down. That would be like a black hole.
