Life is in little things

Have you ever thought about how you would fill a glass of water if you couldn't see the glass and the water and you could only use your sense of touch to do the task? A very effective way is to put the tip of your finger over the edge of the glass. When you feel the water on the tip of your finger, stop - the glass is full. You must be careful, though: this technique only works with cold drinks. For hot drinks, you would have to rely on a little device called the liquid level indicator, which would remind you that the glass is full.
