The floor is lava

The floor is lava is a game in which players pretend that the floor or ground is made of lava (or any other lethal substance, such as acid or quicksand), and thus must avoid touching the ground, as touching the ground would "kill" the player who did so.^[1] The players stay off the floor by standing on furniture or the room's architecture.^[1] The players generally may not remain still, and are required to move from one piece of furniture to the next. This is due to some people saying that the furniture is acidic, sinking, or in some other way time-limited in its use. The game can be played with a group or alone for self amusement. There may even be a goal, to which the players must race. The game may also be played outdoors in playgrounds or similar areas.

This game is similar to the traditional children's game "Puss in the Corner", or "Puss Wants a Corner", where children occupying the corner of a room are "safe", while the Puss, the player who is "It" in the middle of the room, tries to occupy an empty corner as the other players dash from one corner to another. This game was often played in school shelter-sheds in Victoria, with the bench-seats along the walls of the shelter-shed being used as platforms joining the corner, while players crossing the floor could be caught by the Puss.
