What does it mean to put a steel shovel in a bowl of water?
The tension it receives is greater than its own gravity, but its weight is small, so it cannot float. The contact area with water is large, but the weight of a dollar coin is greater than the tension it receives, so it can float \r\n 1 dollar coin, although its contact area with water is larger, or it will be subjected to greater tension if it is replaced by other liquids with large surface tension. If the one-dollar coin is made thinner, it will be subjected to greater tension.
