Smoking Fingers
Remove the sides of 1 or 2 match boxes.
Peel the cardboard off the back of the sides to make them as thin as possible.
Put a light fold down the centre of each strip and place face down on the bottom of a drinking glass.
Light all strips.
Burn until you have nothing but ash.
Tip ash off glass and you should be left with a brown goo on bottom of glass.
Wipe goo off glass onto ends of fingers.
Rub fingers together and they will produce smoke !
PS. Turn off lights and your fingers will also glow in the dark !
