Solids liquids and gases show

Slightly more gentle for the more sensitive ears of younger audiences - years 7 and 8. This activity, a series of demonstrations involving dry ice (carbon dioxide), oxygen and liquid nitrogen, is also well-suited to senior primary or junior secondary pupils.

As well as turning solids and liquids into gases, we also turn gases into liquids and have lots of fun with balloons, bangs and bottle-rockets. This grabs the attention of learners to drive home issues of pressure, forces and states of matter while injecting plenty of excitement.

It is often delivered by trained students, closer in age group to the audience, who can act as role models.
