Whenever I throw anything into the rear of my SUV or car trunk, the second I take the slightest turn at the slowest speed possible, everything seems to roll, crash, and slam into the sides of the trunk with the power of a thousand suns. I don’t know how it’s possible, but that’s just the way science works. This genius invention called the Stayhold is a device that helps you organize and prevent things from rolling around in your trunk while you drive.
