Oscillating Colour Change
We use three chemical solutions to create an oscillating reaction. The three different solutions are mixed using a magnetic stirrer and the colour changes from clear to amber to dark blue. This pattern repeats as the concentrations of...

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...

Ball and Hoop
We use a metal ball and hoop to demonstrate heat expansion. When cool, the ball fits through the hoop, but there is little extra space. The ball is then heated over a Bunsen burner. When hot, the ball doesn't fit through the hoop. We see...

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...

Hero's Engine
We use a Hero's engine model to show how equal and opposite forces can cause propulsion. Two holes are pierced in a metal bottle and some water is added. This is suspended above a Bunsen burner, and as the water boils and leaves the...

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....

Agar Cube Diffusion
We use coloured agar cubes to see how different shapes change the rate of diffusion. The cubes are made using sodium hydroxide and phenolphthalein indicator to give them a pink colour. When these are added to hydrochloric acid, the...

Inflating Glove
We inflate a rubber glove using the gas produced during a neutralisation reaction. Bicarbonate of soda is added to vinegar in a beaker covered by a rubber glove and it expands. The gas is used to extinguish a flame, showing that it is...

Elephant's Toothpaste
We create a rapidly expanding column of foam by mixing chemicals. Hydrogen peroxide and detergent are added to potassium iodide and food colouring to set off a reaction that creates vibrant expanding foam. Chemistry - Reactions -...

Can Crusher
We demonstrate the effects of imbalances of pressure. A metal can is crushed by atmospheric pressure. We add some water to a can and boil it until the can is full of water vapour. It is then sealed and left to cool and after a few...
