EARTH HOUR PARTY SUGGESTION
Participate in Earth Hour without all that bothersome switch flipping by getting a few friends together and putting your lights out with a cocktail or two:
2 shots EverclearEverclear isn't available in Australia as far as I know so locals can substitute Spirytus 95% Polish Pure Spirit (neither has any taste so it doesn't really matter). Warning: be very careful if you're a smoker and stay well clear of candles or you might just light up the night.
2 shots Bacardi 151
1 shot Pepsi
