Everyone has to move around randomly until the leader shouts out “Molecules of ” and they say a number. If they say 6, then everyone has to try and get into a random group of 6 people, any more or less are out, and the last 2 are the winners.

If you say molecules of 1 you have to stand on one foot and put your hands together over your head like a roof of a house, and if you fall, you’re out.

If you say molecules of bacon, then everyone has to get down on the floor (on your stomach) and tap their hands and feet against the ground like sizzling bacon.

If you say molecules of a submarine, you lie down on the ground (on your back) and stick one leg straight up in the air.  Any other object is to be made by the people playing.
