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 ...

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 ...

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 ...

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 ...

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 ...

Sweden’s coasts are facing a UFO problem—reports of "unidentified floating objects"—and they're creating unexpected issues at ...

Have you ever noticed that balloons blown up by mouth don't float in the air, while balloons filled with helium gas do float? To understand this question, let's look at why things float. A person ...

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 ...

Most apes and humans are not built for swimming or even floating. The composition of the human body has a higher proportion of dense muscle tissues and bones. When the lungs are filled with air, all ...

Students will design, test, modify, and optimize a device that uses a chemical reaction to produce enough gas to inflate a bag to make a cell phone float. The goal of engineering is to design an ...
