A hidden feature of water, long submerged, has finally been brought to the surface. New experiments have revealed supercooled water’s critical point — a specific pressure and temperature at which two ...

Host Lloyd Liedtke guides students through hands-on experiments exploring buoyancy, balance and force. Learn why some objects float while others sink, how paddle boats move, and how weight and volume ...

The Water Science and Technology Board (WSTB) was established in 1982 to provide a focal point for studies related to water resources at the National Academies. The board's objective is to improve the ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

Discover the amazing properties of water's surface tension as you make metal paper clips float on water. You'll learn about the forces that hold water molecules together and how insects like water ...
