Mention Mattel and what comes to your mind? Barbie dolls and Hot Wheels? There’s a new line from the toy company which is roughly the size of a credit card and is as slim as a cellphone (which varies in thickness, depending on whether you’re talking about a modern day version or one of those old clunkers), known as Stealth Rides. What makes it stand out (literally) would be its ingenious 3D action, where a single button press will see the “flat” car pop up into a remote control vehicle. You can’t quite get the Hot Wheels Stealth Rides now, but you can definitely stock a few of these early for Christmas as they hit retail stores this August for $25 a pop.
