Back with a bang!

9PTt has just started their Chemical Reactions unit, and I showed them an impressive and scary (for me to light) chemical reaction. It takes place in a ground flask, with the class lights turned off for maximum effect!

1 tsp boric acid + 100mL methanol --> thimethyl borate

The boric acid and the methanol react together to produce trimethyl borate, which produces a beautiful green flame when it is lit on fire.

Reactant + Reactant --> Product

Katherine and Caroline were kind enough to film the experiment for their class.
