This kid-friendly dunk tank combines games of skill, chance, and outright aquatic vengeance for a fun summer activity. Assemble the nearly 5-foot scaffold, then choose a brave soul to stand underneath the water bucket. Step back, and start tossing the included soft balls at the target. Once the target is hit, whoever is beneath the structure will get drenched thanks to physics, gravity, and the regret of volunteering to be the one standing underneath. The tower is completely portable, too, so you can totally take it to work and settle scores.
