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. The players stay off 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.

Growing up, my siblings and I loved playing the classic game “the floor is java,” it taught us so much about coffee brewing techniques.

Spilled coffee beans all over the floor while trying to make my morning coffee
“Could it be? I guess we’re playing The Floor is Java!”
“If I was gonna spill at any stage of the process, this was the best one for it.”
