Being in a cool pool on a hot day—it doesn't get much better than that, right? Well, unless you also have some ice-cold drinks to go along.
Yeah, you can keep the cooler near the pool, but what's even better? Taking it in the pool with you. All you need is a few foam noodles, waterproof rope, and large-lipped container or sorts.
Instructables user macgeek basically just cut some really cheap foam noodles to fit the perimeter of his large plastic container, then used the rope to hold everything into place.
It's simple, quick, and effective. If you have a pool, chances are you already have most of this stuff, so it's essentially no-cost, too.
