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 …

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 …

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 …

Refraction of Light in Water Experiment (Video)

Have you noticed that things look a little funny when you see them through a glass of water?  Some of the aberrations are caused by the imperfection in the glass production. But there is more to it. Refraction is the bending of light as it passes from one transparent medium into another​1​.  This bending by …

How To Make A Rainbow – Simple Science Experiments

How Are Rainbows Formed? Sunlight or white light is a mixture of all the rainbow colors. The different rainbow colors are essentially mixed together to result in a white color. You may wonder why when you mix all the different colors of paint together result in black instead of light. That is because light mixing …
