This week, Brian and Elizabeth show us how to use a humidifier, inner tube, and a light to make little fog doughnuts. Pushing down on the inner tube increases the pressure and forces fog out through the circular hole on the top.

How To Build It:

  • Cover part (about 3/4) of the air outlet in the humidifier.
  • Attach the inner tube to the top of the humidifier.
  • Cover the inner tube with a waterproof material and cut a circular hole in the middle; small holes seem to produce better results!
  • Shine a light and enjoy the science!
