Mattel's super-small "Stealth Rides" aren't making their official debut until the Toy Fair later this month in New York, but for all you know the guy next to you could be packing one... right... now.
They're about the size of a credit card and the width of a cell phone, and with the push of a button they unfold into a remote-controlled car. Apparently the Stealth Riders will come in five models: a "Batmobile Tumbler," and four others that I immediately forgot about once I heard "Batmobile Tumbler."
How it works: the folded-up cards fit into a small case that also functions as the remote control. Just slide the car out, pop it open, and go to town for up to a half an hour. Or however long it actually lasts in real use.
You'll have to wait a bit, though, before you start sneaking this out to cause havoc in budget meetings: they won't be on sale until August, for $25.
