PINHOLE CAMERAS!
Pinhole cameras are made by a dark box on the inside (as little light as possible) with a dark lens, so you cannot see through it then put a pin size hole in the middle of it like we have done with ours (below) but you can either buy them ready made or make them yourselves. Pinhole cameras are like a kaleidoscope effect as in the way it is turn upside down.
here is a short clip on what they do and how they work.
