Pour a glass of water and watch it turn to ice instantly! This step-by-step tutorial will show you everything you need to know about Instant Ice.

Want to make a glass of water freeze instantly on command? What is this supernatural power and who can use it? Discover the secrets to Ice-bending ... in real life.

This could be a fun phase change experiment to try. Dry ice is frozen CO2 -- which needs to stay at a ridiculously low temperature to stay frozen. When you put it in the balloon, it changes phases to a gas -- which is less dense and expands, causing the balloon to fill.

Looking at water and ice with infrared light helps us understand how light and heat are related.

The video introduces mineral properties using common fruit and vegetables as analogies for these five descriptive criteria. The video also demonstrates the orderly crystalline structure of halite (NaCl) using a model made of food (marshmallows and grapes). Comparisons between common substances such as ice and glass versus the mineral definition are made to illustrate the specific nature of the mineral definition.

Now, in a newly released view of Europa's cracked surface, ruddy veins of hydrated salts mixed with chemicals such as magnesium sulfate or sulfuric acid break up bluish slabs of pure water ice. Compiled from data collected by NASA's Galileo spacecraft, this image release only amplifies our fascination for the moon.

Scientists believe there is an ocean hidden beneath the surface of Jupiter's moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity's most profound questions.

We have known for some time that Bárðarbunga was going to do something-we just didn't know what. Because it is covered in ice, we rely on instruments to reveal its behavior.

Now that it has stirred, it is giving us clues about what it is about to do. The clues from the patterns of earthquakes and earth movements reveal two clusters where magma is moving toward the surface, and if it gets there, it will erupt. But whether this will be a gentle or a violent eruption is uncertain at the time of writing.

There is no way to predict when the eruption may happen, but we should get a few hours' notice. The good news for air travel is that both clusters are away from the heart of the main volcano, which makes it less likely that an eruption will produce the fine ash that causes disruption.
