As end of term rapidly approaches, I put together some demos I used to do at this time of year when teaching. A christmas present from me to you.
namely
Screaming jelly baby
copper coins into gold
exploding crisp can
collapsing cola can
contact explosive
exploding sugar and spice
orange volcano

Simplified protocol plus some wordsearches based on the demos.

(I have now corrected incorrect oxidation number in wordsearch)
