The floor is lava is a game, played by people of all ages, in which the players imagine that the floor or ground is made of lava (or any other lethal substance, such as acid or quicksand), and thus avoid touching the ground lest they get burned or otherwise injured. The players stay off of the floor by standing on furniture or the room’s architecture. The players generally may not remain still, and are required to move from one piece of furniture to the next. #Wikipedia
