This week is British Science Week and we have had lots of exciting experiments happening at breaktime every day.
After surviving another of Mr Elstob's renowned explosions on Tuesday, we made some poor jelly babies scream, played with disgusting green slime and made pretty rainbow fizz.
For the finale tomorrow, we are making elephants toothpaste and colour change reactions. Pop along to the science corridor at breaktime tomorrow to watch.
British Science Week is a annual celebration of science, technology, engineering and maths with thousands of events and activities organized across the UK.
