The only thing more divine than floating around in a pool on a hot summer's day is floating around in a pool with a refreshing beverage. But once you're settled in your doughnut shaped floatie, the last thing you want to do is get out to refresh your beverage. Luckily, The Kitchn has a cheap and easy solution for this summertime sadness: All you need is some pool noodles.
Click the link below for the very detailed instructions (and a very helpful slideshow), but the whole thing is pretty easy to assemble. Just grab a plastic storage container and cut a pool noodle into pieces to fit each side, making sure to cut the ends at 45-degree angles so they fit together nicely. Slice each noodle section along the bottom, place them over the edges of the storage container, fill it with ice and drinks, and place it in the pool.
