I have to hard disagree there. To me, the first one is a piece of plastic trash. (Not to mention the guy in the video might be one of the most irritating humans alive.) The second solution is awesome. To each their own, I suppose.
i agree but when the "guys" are coming you are not taking a bucket and fill it with ice and salt, don't you?!
the ice/salt method is known, especially for making ice cream but again the cooler is a much "cooler" way to cool drinks. i guess it can also be takken outside like when camping and you can cool your drinks.
