Today in science year 5 were watching a demonstration called ‘Soda Snake Firework’.
A glass bowl was filled with sand and topped with some baking soda and icing sugar mixed together. Then a bit of Propan-2-ol was drizzled on top of the mixture. After setting it alight the mixture started to caramelise and eventually what looked like a black snake emerged from the bowl.
It did take a few attempts for us to get it right, but we got there in the end!
