How do you make a black hole for a science fair project?

Answer 1

You can't really "make" a black hole, but you can do research, present on the research and do a small demonstration of one of the properties of a black hole.

For example, there are lots of experiments you can set up to measure the force of attraction between two objects. You can use that as a launch pad, then compare that to the estimate gravitational force of a black hole.

Answer 2

It is not possible to create a black hole for a science fair project as they are extreme cosmic phenomena that result from the collapse of massive stars. Instead, you can create a model or simulation to demonstrate the concept of a black hole and explain its properties to your audience. You can use simple materials such as paper, cardboard, and paint to visually represent the idea of a black hole.
