Happy Filled Glass 4 (Happy Filled Glass 4)
You'll see the lucky glass again in Happy Filled Bottles 4. Only today he was sad again, as he turned out to be completely empty. You need to fix this, and to do this you need to fill it to the brim with clean, life-giving water. Using a black felt-tip pen, draw lines as you see fit, but at the same time you need to pay attention to where the water flow is moving and not spill precious drops on the walls of the glass. If the liquid fills the glass below the specified level, you will have to restart the mission for that level in Happy Filled Glass 4.
