T.2.7 Drinking Bird a Love Meter Drinking Bird - The bird dips its beak into a beaker of water "taking a drink" and rotates back up. Cooling by evaporation from its beak draws up a colored liquid (methylene chloride) through a tube in its body overbalancing the bird so it takes another drink. This action repeats indefinitely. Love Meter - Hold this device in your hand and heat from your hand boils methylene chloride causing it to flow through an intricate series of tubes. |
