1. Water transport.
Rules of the game: Men and women stand in a row alternately, each person takes a disposable paper cup (slightly better quality), and pours half a glass of water into the cup at the head, which can only be passed from the head to the tail by mouth. The team with the fastest speed and the most water wins, and members of other teams can watch and see who helps their mouths with their hands. The foul must be passed again from the front row.
Tip: Before speaking the rules and starting the game, pour a few glasses of water to show fairness. There shouldn't be too many people in the game, about 6-8 people. Before saying the name of the game, let each team send a few men and women.
