One day, mother crow took her little crow to the park to play. They practice flying freely in the air for a while, and then fall on the grass to catch insects. Play with them. They are thirsty and want to drink water.

Suddenly, they found a big bottle of water on the grass. So, look good. But the bottle mouth is too small and there is too little water in it. Their big mouths can't reach water. What should we do?

The clever mother crow had a brainwave and found a straw from the nearby grass and inserted it into the bottle mouth. Problem solved. They drank the water in the bottle freely with straws and were very happy.
