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.
