1 measure blue curacao

1 measure Bailey's Irish Cream

top up with one pint cider -- (or lager if you prefer)

The end result is a sort of greenish-brown liquid with scummy bits floating in it and a THICK layer of scum on top. Tastes wonderful, though, especially if you dunk chocolate bars in. (These are referred to as Control Rods, and the bar of preference is a Toffee Crisp, if only because the crisped rice pieces start floating around in the drink and making it look even nastier)

The nuclear wastes I've seen mix blue curacao and orange juice (and vodka). Turns everything a very nice shade of fluorescent green
