Bouncing Eggs
We use vinegar to remove the shells from eggs without breaking them. Two eggs are placed in a beaker of vinegar, but one is half coated with clear nail polish. The exposed shells dissolve over time and the eggs swell as more water moves...

Anaerobic Respiration: Observing Yeast's Oxygen-Free Energy Production
We use yeast to let us observe anaerobic respiration. The yeast is added to warm water and glucose. A layer of oil is placed over the solution so that no oxygen is available. The solution starts to bubble and the gas produced passes...

Cloud in a Bottle
We create a cloud in a bottle using warm water and smoke. Some warm water is placed in a plastic bottle and then some smoke is drawn in using a glowing splint. The bottle is sealed and then squeezed and released. The change in pressure...

Frozen Balloon
We lower a helium-filled balloon into liquid nitrogen to see how the change in temperature affects its volume. When it hits the cool liquid nitrogen, the gas inside contracts and the volume of the balloon decreases. When it is removed...

Burning Bubbles
We investigate the properties of two types of gas bubbles: methane gas bubbles and bubbles of the gas we breathe out. The air-filled bubbles sink and we are unable to set them alight, while the methane bubbles float upwards and are...

Screaming Jelly Baby
We add a jelly baby to a boiling tube containing potassium chlorate. When the chemicals react, gas is rapidly produced. The screaming sound is created as the gas escapes from the tube. The sweet burns brightly as the reaction occurs.
