Electricity is a recent discovery. Think of 12 things to do when there's no power.

1} Light a candle and make mini smores.
2} Turn on the battery-powered radio to Kiss FM, then turn on some flash lights and flicker them on/off, flash them back and forth, etc, and have a rave.
3} The classic: tell scary stories!
4} Make up your own classic radio show and run through episodes until the power comes back on.
5} Run around poking people.
6} Leave people in your area creepy voicemails.
7} Make weird sounds to freak people out.
8} Try to navigate the messiest room in your house.
9} Play the guessing game.
10} TP the living room with your eyes closed.
11} Act like a ghost.
12} Make a list of what you'll do when the power comes back on.
