This summer has been unusually hot, and it is almost impossible to go outside on any given day. In order to experience a little coolness, we have prepared a tub at the entrance and use a fan to blow air while playing in the water for short periods of time. The children were so happy to touch the water that they got into the tub and got into it. The children are happy to touch the water and enjoy themselves by pouring water from the top with a container in one hand, tapping the surface of the water with both hands, and looking at the water coming out of the hole like a funnel. They enjoy touching the water in their own way. I wonder when they will be able to play dynamically in the water.
