The Crisp Flavour Test.
Choose 2 students with no allergies, then blindfold them.
Before the assembly you open up the crisps at the bottom and swap over the contents into different packets.
Once blindfolded, you tell them they have to guess the flavour.
They will shout out ‘cheese and onion’ while the whole assembly/year group are saying, ‘no no it’s salt and vinegar’ etc
Don’t judge by appearances.
Have the courage of your convictions.
