Sometimes during electrical
storms, the electricity in the air can form into strange glowing balls of
energy. These are quite rare but there have been enough reports of them to
believe they exist. Ball lightning is usually bright white, yellow or pale blue in
colour and can range in size, from only a few cm across to much larger.
It is
often seen to drift across the sky or into people’s houses through open
windows. Sometimes it can be attracted towards power sources such as a plug in
the wall, and has been known to short out the electrics or explode in a flash
of light when it makes contact with something.
