Can anyone tell me how to make a prism (rainbow) on a surface with water and torch? No stupid answers.

Answer»

When light goes through a glass of water – it also splits into a rainbow.

To GET ready – take a piece of paper and CUT a slot into the middle of it. Tape this onto the SIDE of a smooth/clear drinking glass so that the sun’s rays can PASS through the opening onto the SURFACE of the water in the glass.

You will NEED to do this on a very sunny day (or try a darkened room with a strong direct light source.)

Make sure that the glass of water is VERY FULL. Place the glass on a white floor or white piece of paper, making sure the sun’s rays are shining through the slot in your paper and hitting the surface of the water.

You should see a mini-rainbow appear below the glass!
