Here’s a guy named Franky Zapata using a “dolphin jetpack” called the Flyboard that lets him leap from the water and fly through the air just like, um, a dolphin:
It also lets him hover above the water and do acrobatics; the difference between this and your regular off-the-shelf jetpacks is that you get to both zip beneath the water’s surface and hover above.
It’s $6,400 if you’re interested. I don’t think you can buy it from Walmart yet. Maybe Sky Mall.
