The figures became sad. They want to play with them a little. You have a chance to cheer them up. And to do this, just fill them with water. Open the faucet, measure out a certain amount of water and wait for it to fill the container. Ensure that the water reaches the level indicated by the dotted line, but does not overflow. The faucet must not be opened again. So it’s worth turning on the eye and trying to immediately measure the right amount of liquid. And may you be lucky!
