Outside the Lines: Water Jetpack!
"You have been dreaming about flying a personal jetpack for way too long. Your wait is finally over!"
Yes, thanks to JetLev, you too can now fly like a superhero -- or at least, like a superhero with a jetpack. It's a water-propelled device, so you do need to be over water, but it is still a machine pulled out out of my childhood dreams and wishes that I sincerely hope will soon be available at a vacation spot near me.
