No, this is not another mass prank from Improv Everywhere --it's the latest commercial for Sony cameras. Much in the spirit of spring break, the company flooded the streets of Miami with 120 million gallons of bubbles. For the purpose, they used the world's largest foam machine, which pumps out over 500,000 gallons of foam per minute (apparently, it can fill an Olympic swimming pool in 24 seconds). Don't you just wish you were there?
