A demonstration of the classic displacement reaction that takes place when aluminium powder is mixed with the oxide of less reactive iron and lit.

IMPORTANT! Do not copy this without familiarising yourself with the CLEAPSS guidance, notably bulletin 92.

In future I will
- wear a lab coat, fully fastened and gloves (flash-proof not rubber).
- use a smaller filter paper. The reactants will drop into the water as soon as the mixture lights and continue safely there, as you can see it does in the video. Yes it is that exothermic.
- fill the beaker a third full of sand. This avoids breaking a beaker every time you do it.

Once again, I have not covered all the health and safety, either in the video or in this description, so check out CLEAPSS. If you can't log in to CLEAPSS consider whether you should be doing this at all.
