Chill the water undisturbed for 2-3 hours. The amount of time needed to supercool the water will vary based on the temperature of your freezer. A good measure is to also put a bottle of tap water in the freezer. Once the tap water is frozen, your pure water should be supercooled and still in its liquid state.


Allow about 15 minutes for the water to cool below freezing. Alternatively, you can insert a thermometer into the glass of water. When the temperature of the water is below freezing, the water has been supercooled. You can make the water freeze by pouring it over a piece of ice or by dropping a small piece of ice into the glass.


The impurity thus triggers a transition from liquid to solid, water to ice. So if you want to make a supercooled liquid yourself, don't try it with tap water or cloudy beers: They have too much ...


Experimental Procedure Procedure for Supercooling Water. Cut a circle from the cereal box to use as a cover for the plastic cup. Pour a small sample of distilled water into a clean plastic cup (enough to fill about 1/4 of the cup) and place the cup in the center of the bowl.


Fish that rely on supercooling for survival must also live well below the water surface, because if they came into contact with ice nuclei they would freeze immediately. Animals that undergo supercooling to survive must also remove ice-nucleating agents from their bodies because they act as a starting point for freezing.


You make an excellent point about the viscosity of the supercooled water. Extrapolating from the viscosity vs. temperature of stable liquid water, the supercooled water might have close to twice the viscosity of water at 0°C. Since we're so used to seeing bubbles in normal water, that might well be enough different for David to have noticed it.


By cooling the water slowly, the water remains liquid below its freezing point. This is known as 'supercooling'. When the ice is dropped into the water, the water suddenly freezes and turns into ice. This happens because the ice cube allows the supercooled water to grow new ice crystals. The freezing point of water is 0°C. This means that ...


Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid. A liquid below its freezing point will crystallize in the presence of a seed crystal or ...
