Solo Cup Lines
You commonly see these red Solo cups at parties and events, but not many people know the horizontal lines on these cups can actually tell something. The first line means there is one shot of liquor in the cup. The second line means there are five ounces of wine. Lastly, the top line means there are 12 ounces of beer.
Jerry Can Handles
You might know that a Jerry can holds fuel, but do you know the reason behind its three top handles? The design actually allows even fuel distribution inside the Jerry can when you carry it. If another person is helping you, the two of you should each hold an outside handle. If you are carrying it alone, stick to the middle handle.
