Solo Cup Lines
Do red solo cups bring you back to the days of college parties? We doubt that you ever noticed the horizontal lines on these cups. The first line is an ounce or shot of liquor. The next one is five ounces or one glass. The last one is twelve ounces or an entire beer bottle. Pretty handy, isn’t it?

Jerry Can Handles
If you like traveling and camping, you must be familiar with Jerry cans. However, do you know why there are three handles on the top? The cans were designed that way to ensure that fuel is distributed evenly. Two people should hold the exterior handles, while solo carriers should hold the middle one.
