Colourful glass hand boiler contains brightly coloured liquid that boils from the heat from your hand. Watch the liquid move from the bottom chamber through the twisty tube to the top chamber. These were sold in the 70's as love meters ( to see how hot you are) Now they are just an awesome science toy and visually stimulating.
