What you need

  1. a sheet of paper
  2. cotton thread
  3. scissors


Instructions

  1. Cut a thick spiral shape in the piece of paper.
  2. Make a hole in the centre and thread the cotton through it.
  3. Hang the spiral above the radiator.

Results & explanation

The spiral should start to spin slowly. The radiator heats the air around it so the particles have more energy to spread out. This means the air is less dense and rises upwards. The rising air pushes on the paper causing it to spin.
