Supercooling water and snap freezing
Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water.
Heavy Water Production
Information on heavy water, used for nuclear weapons. Heavy water, or D2O, is water in which both hydrogen atoms have been replaced with deuterium, the isotope of hydrogen containing one proton and ...
Hot Water Freezing?
A brief discussion (with a slightly disbelieving tone) of why hot water freezes faster than cold water. Links to a related section on the Mpemba Effect.
Water Tower
Applet showing water flow from a hose as height changes. The amount of water in the tower can be varied.
Water Pressure
An applet showing how water flow is affected by pressure and how water towers work.
Boil water with shockwave
With an animation you can alter the amount of water and starting temperature to estimate how long water will take to boil. The animation will run and your estimate of time evaluated.
That Sinking Feeling (Water Temperature and Density)
Why does the water always seem colder at the bottom of a lake?
Exploding water
In this video mythbusters find out how likely it is that you could superheat water in your own microwave.
Supercooled water
An extensive Q&A about supercooling water and what factors can lead to it.
What is unfreezable water?
This page explains different ways that water can remain unfrozen at low temperatures - including dissolved solutes and supercooling.
