This simple demonstration shows vapor pressure. Holding one bulb in your hand increases the temperature and thus the vapor pressure. This forces the liquid into the other bulb and causes it to appear to boil.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Place the palm glass apparatus on the demo table.
