Freezing a flower in liquid nitrogen

You will need:

  • Unless you have liquid nitrogen and formal training it's safer if you don't try this experiment


  1. Read the explanation below after watching the short video on liquid nitrogen freezing a flower.

Liquid nitrogen is -196 degrees Celsius.
The liquid nitrogen freezes the water inside the petal cells quite easily. When it has warmed up, the flower becomes quite slimy as the cells have broken apart (lysed) and the flower petals have lost their structure. Try lettuce or a banana too!
