Today we launched rockets powered by a chemical reaction!
We took a matchhead and wrapped it tightly in foil and wrapped the foil around a bamboo skewer, so that the expanding gas could only fly out the back of the foil cylinder pushing the foil off the end of the skewer like a rocket!
It was a huge success and we are confident that the rocket was powered by a chemical reaction because the reaction:
-Gave off heat
-Gave off light
-Changed colour
-Produced a gas
-Gave off a smell
-and could not be turned back into a unburnt matchhead
So overall a good afternoon of school.
