Description:

Room temperature water is dripped onto a hot plate.  The temperature of the plate is so hot, the water drops bounce and dance due to the Leidenfrost effect.

Apparatus 
 
  • hot plate
  • cup of water
  • large pyrex beaker of water

Procedure
  • Place the large pyrex beaker of water onto the hot plate.  The beaker will help to regulate the temperature of the hot plate.
  • Turn on the plate and heat it up as you would to bring the beaker to a near-boil.
  • Drip some water carefully onto an exposed area of the plate.  If the temperature is hot enough, the water droplets should dance about.
 

 

Safety 
 
  • Be very careful using water around electrical devices.  
  • Drip the water onto the plate is VERY small amounts.  Too much water can lead to the water "exploding", potentially burning your hands or face.
  • Be careful to protect yourself against burns from the produced steam.
