Are there any objects you can trust these days? With cameras and their associated gadgetry getting smaller and smaller, virtually anything can be spying on you at any time. Just look at this spying Coke can, for example.
These fake Coke cans have a tiny camera and DVR built inside, as well as a fake bottom that can be removed to reveal a USB port and on-off switch. They also have a remote control so they can be started and stopped from afar. If this is a camera, what else is hiding spy equipment? Maybe it's best not to think about it.
