You need a bit floor space for this. Not sure what the minimum suitable age would be.
Players form a circle.
In the middle is a blindfolded player who is given a wooden spoon.
A saucepan is placed upsidedown on the floor somewhere within the circle.
The blindfoldee has to find it with the spoon and bang it.
Players in the circle can say ‘warm’, ‘cold’, ‘hot’ as appropriate.
They can also drum their hands on the floor to give a hint as to where the pan is.
Note: VERY NOISY when played by cub scouts!
To think that London, or anywhere else for that matter, does not belong to any one demographic
