Walking the line, touching your nose, saying the alphabet backwards, these sobriety test are old and will make you look like an idiot. Usually it is safe to assume anyone who does these test without an officer present is pretty schmammered. But what if you want to discreetly test your cognitive ability after throwing a few back? Grab one of these nifty puzzle glasses. At first glance they look like a simple rocks glass but at the bottom lays a ball maze puzzle. Though this test is not very accurate, it is fun and a good start.
These glasses are expected to sell for $20 a pop and should be available later in the year. Get one here.
