Ever wondered why your soda can on a flight sometimes looks a little weird? Turns out, Southwest Airlines is spending millions to stop drink cans from popping or exploding in crazy summer heat—think Phoenix or Vegas hot. Exploding cans have actually injured flight attendants! Now, Southwest is rolling out refrigerated trucks to keep drinks (and workers) cool. So next time you sip at 30,000 feet, thank the fridge on wheels! #Business #Industry #TravelHacks
