A typical shot is 1.5 oz, so you couldn't use that line to mix a drink. A typical glass of wine is 4 oz. Why would they choose 1 oz and 5 oz? I'm guessing it's either false (I'd have to measure to know :) ), or that the lines are coincidence, or at the very least they weren't thinking of alcohol when they made the lines.
Have you ever tried filling the cup to the 12 oz mark with Gummy Bears, then filling it to the 13 oz level with Vodka - cover with a good plastic wrap and leave over night. Next morning its breakfast, lunch or dinner - all you need is a toothpick or small fork!!
Ten thousand points to Linda for providing an interesting fact amongst the thundering noise of Google+'s "What's hot" feed. That is actually pretty cool. As a kid I thought they were rocket stage separation points.
I unfortunately moved past the cup and go right for the source, pirate style. Cups are the coolest thing since sliced bread..which is kinda pointless as well. I say slice yer own bread and drink booze str8 from the bottle or can...
wow. and this info was just under our noses the entire time! the world gets more interesting each day. seriously, thanks for sharing. this is helpful info. good trivia when standing around the keg or playing beer pong.
Did anyone actually read the reddit comments? 1) The measurements are false. 2) Plastic engineers are darn cool. 3) The design provides stability and keeps the cups from being too hard to pull apart. One of the rare times reddit comments were overly intellectual.
