Mad Science - Solids, Liquids and Gasses Workshop

Scientists have ideas, they experiment and tell people what they have learnt. Let's have fun being Scientists!

Gravity is invisible. It pulls everything down to the ground.

When this bottle is turned upside down a battle between air and gravity begins.

The liquid is fighting to get to the bottom but has to travel through a small hole to get there. Air is holding the liquid back by trying to force it's way to the top.

But there is a way we can help the liquid and air make room for each other.

We can make a vortex by swirling the liquid around. A hole is then made for the air to escape allowing the liquid to pass to the bottom bottle.

A vortex is a mass of whirling liquid!

It's hard to capture on our photographs but this is what the liquid inside the bottle is doing.

Our next experiment was to add orange and raspberry vitamin tablets to a liquid. The liquid was water.

A chemical reaction took place immediately. The vitamin tablet dissolved, the liquid changed colour and started to bubble. You could hear the fizz as the vitamin tablets dissolved.

We tried mixing the orange and raspberry liquids together. This turned the liquid a darker shade of orange.

Let's try to make some carbonate dioxide. We will need a funnel, a measure of bicarbonate of soda (baking powder), a flask with a measured amount of white vinegar and a balloon.

Place the balloon over the small end of the funnel.

Take the balloon off the funnel and carefully place it over the flask containing the vinegar.

Now tip up the balloon so the powder falls into the vinegar. Sit back and watch what happens.

Can you hear anything?

Watch what happens when nail varnish remover is poured over a piece of polystyrene.

A chemical reaction takes place and the solid piece of polystyrene melts.

Photograph of Mad Science Visit

The polystyrene changes back into a solid but it is much smaller than the original piece. Why? Because all of the air has escaped!

Please click on the play button above to see what happens when some fruit flavoured mentos are added to a bottle of carbonated cola. Can you explain what has happened?

Animated Thank You Mad Science that was another amazing workshop!
