BACtrack Breathalyzer

If you host a lot of parties or simply do a lot of drinking, you might want to check out the BACtrack Breathalyzer ($72). This nifty gadget uses BluFire sensor technology to provide quick, accurate blood alcohol level readings, keeping you (or your guests) from over-indulging and getting behind the wheel — or worse, leaving with their ex-wife.
