Get the biscuit from your forehead to your mouth and eat it without using your hands
biscuits (or after 8's if it's a warm room!)
Either lay flat on the floor or stand with your head tilted backwards. Put a biscuit on your forehead and using on your facial muscles, heads tilts and gravity, get it into your mouth and eat it within a minute.
This can be made more fun by racing two or more players against each other!
