Electricity and I have never

For electricity you have to stand in two lines and hold hands with the person in front and behind
you also need to close your eyes only the person in front keeps there eyes open and the teacher
flips a coin if it's on heads you squeeze the person behind yous hand then it goes down the line
until the person at the backs hand has been squeezed and they then run to the front until you get back to the person who started.But if it's tails and you run to the front two people have to go to the
back.
