From Gary Collins
It shouldn’t be necessary to go to the lengths of Sean Langley and colleagues
and actually get inside the fridge
(7 July, p 57).
The light switch of the
fridge will operate before the door is fully closed, so it is possible to see
that the light goes out before the door closes completely.
I suppose, though, that you can’t prove that the light doesn’t come on again
once the door has closed…
