CLEAPSS Supporting practical science and technology
SRA002 - Dust explosions using cornflour, custard powder, icing sugar, lycopodium powder, etc.
A complete set of risk-assessed instructions for safely demonstrating the explosive capacity of powders.

Note:- These activities are designed to be carried out individually as part of a lesson conducted in a secondary school science laboratory. The procedures are not intended for use in other contexts – for example in a primary school classroom or other non-science or non-school setting. 

The activities should not be used to create a ‘whizz bang’ science show. 

Experience suggests that using a number of activities one after the other in this way gives rise to unpredictable additional risks which the individual procedures may not manage appropriately.
