How much water do you need to keep a cruise ship afloat? Less than you’d think. Archimedes’ Paradox lets you float a huge object in just a gallon or two of water. (It also shows why you’d need a ...

A: “An object will float in water or in air because the object is lighter than the air or the water it displaces,” notes MU physics Professor Karen King. All forms of matter such as gases, liquids and ...

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 ...

Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth, and ...

Some objects float in water and other sink. But did you know that you can change whether something floats or sinks by adding a substance to the water? Let's try it and see! Pour water into a cup until ...

Density describes substances based on much mass they have in a certain volume. Less dense solutions and objects float on top of solutions of greater density. Disposal: Pour the liquids out of the ...

It looks like "Harry Potter" magic, but it's just acoustic levitation: Researchers have created a device that uses sound waves to make liquid droplets and small solid objects float in the air and ...

A planetary scientist has identified the largest-known solid object in the Solar System that could float in a bathtub. The rock-and-ice body, which circles well outside the orbits of the planets, is ...
