Tornado in a Glass

Tornados can be devastating. It can destroy large buildings, rip roofs off of houses, uproot trees, drive sticks into trees and hurl cars hundreds of yards away. They can even pick you up and literally drop you somewhere else. A tornado, also called twister or cyclone, is a violent rotating column of air extending between the Earth’s surface and …

Static Electricity and Water

Here is a simple physics experiment using a property called static electricity.  Every object is made up of small particles called atoms. These particles are extremely small and you cannot see them without a microscope. There are two types of charges in every atom — positive change(s) and negative charge(s). Only negative charges are free …

Make A Square Bubble

Water molecules (and also liquid soap and glycerin molecules) tend to stick to themselves. This cohesive force creates surface tension. (Note: Water by itself doesn’t form long lasting bubbles because a thin layer of water molecules evaporates too fast. By adding soap and glycerin, the “skin” of the bubble is more stretchy and water is …

What Is Surface Tension | Cool Science Experiment

Surface tension is the glue that binds water into a cohesive sphere and the force that makes water bead up on a surface. It is one of the amazing properties of water. Surface tension in water is created by the attractive forces between the water molecules It can be broken up. In this experiment, we …

Hovercraft & Friction Experiment

Friction is the force created when two objects move across each other to oppose the movement.  An object gliding on the floor stops because of friction. When friction is reduced, a gliding object moves faster, farther and for longer. This balloon hovercraft can fly across the floor because air has less friction than the floor. When …

Cartesian Diver Experiment (Video)

How do fish float and sink? This classic experiment is called Cartesian Diver, named after French scientist, mathematician and philosopher scientist, René Descartes. It demonstrates the principles of buoyancy and density and explains how fish dive or rise in water. Buoyancy: the force of buoyancy on an object is equal to the weight of the water displaced by that object. Density: if an object …

How Are Ocean Currents Formed | Water Convection Experiment

How Are Ocean Currents Formed Ocean currents are formed in several ways. They can be created by wind, by gravity, by events such as earthquakes. They can also be made by density differences in the water. Density in the water changes when temperature or salinity varies. In this experiment, we will investigate how temperature can affect …

Magical Floating Water Trick | Science Experiment

Can water defy gravity and float in midair? Not really, but with some help, it can appear to be. Air molecules, which we cannot see with naked eyes, are constantly moving and bombarding everywhere. The resulting force is air pressure. Normally, the air pressure above and below the water are the same. When equal forces …
