What you need

A clear plastic bottle

A torch

Kitchen foil

Sticky tape

A dark room with a sink

Instructions

  1. Wrap the bottle in kitchen foil, leaving the bottom bare.
  2. Fill the bottle with water, switch on your torch and turn off the lights.
  3. Shine the torch through the bottom of the bottle and start pouring the water into the sink. Keep the torch close to the bottle at all times.   

Results & explanation

Almost all the light from the torch is reflected every time it hits the edge of the stream of water, so the light follows the path of the water and you see a spot of light where the water hits the sink.
