Tropical freeze

Cool a bottle of water in the freezer compartment of a refrigerator and it is possible to supercool the water below its freezing point for a short period of time. If one removes the bottle and gives it a sharp bang on a hard surface the rapid formation of ice crystals ensues in what is popularly referred to as the ‘instant ice’ experiment. I’ve been trying to capture the instant ice freezing experiment on camera for several weeks now without much success.

One of the biggest problems of doing this experiment in the tropics is that as soon as the bottle is removed from the fridge condensation forms on the outside of the bottle. This prevents one seeing whats going on inside.

If you try this at home I can only repeat the advice given on several You Tube movies; use as many bottles as you can and keep monitoring them to arrive at just the right moment to take them out by trial and error. My 600ml bottle took somewhere between one and a half to two hours.
