Demonstrating Chemistry: Top of the Flops

Expert chemists from the Royal Society of Chemistry and  CLEAPSS demonstrate what happens when some  demonstrations don't go according to plan and explain why this happens. They also give some alternative approaches to classic experiments.

Problems associated with cracking hydrocarbons, white phosphorus, making chlorine gas, and making copper sulphate crystals are demonstrated, and the experts give some top tips to make school science experiments a success.
