* Demonstration Assemblies for the whole school

These last 45 to 60 minutes. (Normally based on Gases in the Air) Experiments will be demonstrated with liquid nitrogen (a very cold liquid), dry ice (solid carbon dioxide), oxygen, acetylene, hydrogen and helium. There will be some loud bangs and some setting fire to materials.  Some minor reactions including colour changes are included. The performance will emphasize states of matter changes, combustion and what is and is not a reversible change.

'Your lechor [sic] was fantastic, with all that blowing up and stuff, we especially liked your joke about the banana split. We liked the range of activities such as : the balloons, the egg, frosen [sic] flowers, the huge udder, pink frothy monster, disco-liquid (the one that changed couler [sic]) , and loads of others.
To be honest we thought [sic] is was going to be boring, like talk and talk, but it was totally [sic] differant [sic]. We wish you could come to our (own) school.'
By pupils from Bishops Caundle Primary School
