Create a solar powered oven using a pizza box.

Solar powered pizza box oven made from aluminum foil

We can’t provide cooking lessons but we sure know how to make a cool little oven – out of a pizza box! And while we’re at it we’ll learn how thermal collectors are able to collect sunlight and convert solar radiation into heat.

Dispersive prism splitting sunlight into colors

Light traveling in a straight line appears colorless. But there’s more to light than just colorless nothingness. When light passes through a wedge-shaped piece of glass called a prism, the light is separated into 7 different and unique colors. You see these colors when light passes through rain or moisture producing a rainbow.

Believe it or not, scientists are still arguing precisely about what scientific principle should be used to explain why an airplane can fly. One explanation, the Bernoulli Effect, is commonly used to describe the phenomenon of flight. In this experiment, we demonstrate the second explanation – the Coanda Effect.

Gyroscopic inertia – a strange, complicated word – is a force common all around us. It explains how we are able to ride a bike, how planes navigate, and how a figure skater is able to do those lightning fast spins. Here’s a simple experiment that’ll clear up this confusing concept. Note: the hardest part…

Ever wonder why igloos are dome shaped and not square? Ever been amazed at how a suspension bridge can hold the weight of hundreds of passing cars with little or no apparent support underneath it? This experiment demonstrates how arches are used in architecture not only for aesthetic appeal but for a very useful and…

Four blue, red, black and green BIC pens and four pen caps

Pascal’s law has many practical applications, including hydraulic lifts, brakes, and jacks. It is also used in many industrial and manufacturing processes, such as in the production of plastics, metals, and chemicals. Here we will demonstrate Pascal’s law with a pen cap and plastic bottle.

When a person stretches out flat, more water pushes against them because their body is spread out more, which creates more upward force and causes them to float. Conversely, when they curl up into a ball, less water is pushing against them, which reduces the upward force and makes them sink. Want to test this…

An original Mathmos lava lamp, model "Astro", as it was sold during the 1990s

Lava lamps were immensely popular in the 1970’s. For some reason, your parents thought it was very fun to sit there and watch colorful liquid in a bottle swirl aimlessly around. They probably even chanted “Oh wow, the colors, the colors.

Eggs in salted water and in pure water from Six Weeks Of Vacation (1880)

Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space, the denser it is. Although we often confused the two, density and weight are actually two different measurements. Weight is defined as the mass of an object times…
