If
you
carry a can of soda everywhere you go, people will think you're
addicted to the stuff. Let them. Only you will know that rather than
quenching a constant thist, you're gathering information. The can
conceals a DVR with a 4 GB internal memory. It records 640 x 480
resolution at 30 fps and runs on a rechargeable Li-ion battery. Just be
sure to remember not to try to chug it.
