Who doesn’t know the red Solo brand cups? They are at almost every party! We’re all familiar with them, and with the random red lines around them. But did you ever wonder if they were there for a reason? Probably not, and that’s what we’re here for. Apparently, these lines are not there allocated randomly… any guess as to what might be their function?
Each line in the cup can serve to measure the quantity of liquid for the different kinds of alcohol. The bottom of the line is for a shot of liquor, the middle line is a recommended dose of wine, and the upper lines are there to mark the ideal amount of beer.
