Entering the pool is a popular activity for people of all ages. It can be done in a variety of ways, such as splashing (6 letters), betting (3 letters) or plunging (6 letters). Splashing involves making a big SPLASH in the water, usually with a jump or dive. Betting is when two or more people make a wager on who can do something in the pool first. Plunging is when someone dives into the pool headfirst. All three activities are fun and exciting ways to enjoy the pool.
