Theory:

 ll plants need water to survive. This being the case, one flower does have a lot of water in it.  When water turns to ice, it becomes very hard and brittle. Since water has a much higher freezing point than liquid nitrogen, the water can be frozen very quickly when the two liquids come in contact with each other

 

When a flower is immersed in liquid nitrogen, all the water in the flower will freeze in very little time at all. Once the water in the flower has frozen, the flower itself becomes very rigid and brittle. When the flower is smashed, you can see just how fragile it has become.

 

Apparatus:

  • flowers 
  • liquid nitrogen
  • tongs

 


Procedure:

    1. Pick up a flower with tongs and dunk it in a container of liquid nitrogen.
    2. Wait until boiling stops (shouldn't take more than 10 seconds).
    3. Raise the flower out of the liquid nitrogen and drop it on the ground or smash it with the tongs.

 


Safety:
 

Be very careful when using liquid nitrogen, wear safety goggles and cryogenic gloves.
