Hi, Does anyone know how to make a star projector @ home? Answered

When I was in elementary school, our science teacher simply punched tiny pin holes in a can and stuck a flashlight inside.  In a dark room, it will make for a very simply star projector.  The brighter the light, the better.

You can get focused beam LED lamps, and if you put anything in front of them it'll shine almost exactly the same thing on the wall - a filter with laser-cut holes would make a cool pattern Realistic ? I dont know how that works :D
