Chances are you have no idea who Mariano Martinez is, but it’s likely his invention of the first alcoholic slushie machine has made the nights of many as blurry as they are unforgettable. 

In 1971, he tinkered with a soft-serve ice cream machine to create the first frozen slurpee-type alcoholic beverage machine, forever upgrading crushed-ice margaritas to the dangerously delicious drinks we’re familiar with now. That machine is now on loan at the Smithsonian Museum in Washington D.C. And it didn’t just give us frozen margaritas. It gave us a parade of frozen painkillers, palomas, frosés, caipirinhas…
