For: even number of boys and girls, at least 4
What you need: a CD
Sit all the players around in a circle, preferably boy-girl-boy-girl.
First person starts the CD around the circle, using only their tongue. You must pass the CD using your tongue and the hole in CD. If you drop the CD, you are out.
The game continues until there are only two people left in the circle. Before you start the game you have to decide what the prize is. For example, it can be 3 minutes in the other room for the winners, or anything else. Use your imagination, because sky is the limit 🙂
If you don’t have the CD, you can think of some other object that will be suitable for this type of kissing game, for example a pencil, a playing card or a spoon.
