Hot Tub High Dive. Watch out for the flying foam! Pour the included demo bubble solution into the tub unit, spin the spinner, then press the big red button the number of times shown to send the diver up or down the ladder. Every press of the button increases the amount of foam in the tub. Once the diver reaches the top of the ladder, he will fall into the tub, launching a ball of suds at the unlucky player. The only player not to cause the diver to fall and the foam to fly wins the game.
