Former elementary school teacher Matt Shurtleff — known to many students as “Matt the Mad Scientist” — demonstrated how sound waves move using water and lasers.

Researchers have now created a new type of glass using nothing but sound waves and salt. Sure, that might sound like one heck of a science experiment—and in a way, it is—but it's also a major ...

Watch frost form before your eyes as you learn about deposition – the process where water vapor transforms directly into ice crystals. You'll discover how salt affects freezing temperatures and see ...

In this experiment, you'll discover how salt can help a string stick to ice. This simple demonstration shows how salt affects ice's freezing point and creates an unexpected result that seems to defy ...
