Turn your pool into a light show at evening with the Kaleidoscopic Pool Cruising Fish. Not only will it illuminate the pool with an array of colored lights, but it will swim along at a rate of 50 feet per minute. That will give the light show enough variety to cover you for an entire night of entertaining by the pool.

There are countless options when it comes to tricking out your pool with lights, but the Kool-light-o-scope takes things a step further with spinning LEDs that “create continually changing patterns of light and color on the bottom and sides of your pool.” Basically it turns your pool into a wet disco and / or a giant drug-free trip.

Finally, a sport fat kids can excel in. When it comes to cannonball splashes, a little extra weight gives you a distinct advantage.

Being in Mexico for the week on business, I just couldn’t pass up the opportunity to share this Inflatable Fiesta Cooler. The site doesn’t mention it, but as far as I can tell it is a dual purpose item. It will keep you beer cool all night, and when the beer is gone you have a swimming pool. The swimming pool idea is only cool if you and/or your guests have had enough beer out of it. I guess in this case, as most, alcohol=fun.
