Game rules

Preparation: 2 or more people, a large cup, a light cup that can float on the liquid surface, and a bottle of drink. Test with clean water first: the small empty cup must float stably after being placed in it.

Pour the large cup until it is about two-thirds full, and then gently place the empty small cup in the center of the liquid surface.
Use rock-paper-scissors to choose the first player. Players take turns pouring drinks into the floating cup clockwise, and at least one drop must enter the cup each round; you decide how much or how little you pour.
After stopping pouring, the small cup remains floating for three seconds before the round is completed and pass to the next person.
When it's your turn, if the small cup overturns, fills with water, or sinks to the bottom of the large cup, you lose the game.
Empty and prepare two new cups, and the loser starts the next round. The penalty portion size will be agreed upon separately before the game starts, so the large cup does not have to be regarded as a required portion.

Equipment: If the empty cup cannot float, it means that the cup shape or liquid level is not suitable. You should change to a lighter cup with a wider bottom.
