Summer and pool

We started the summer.
Do you know how I found out about this?

My husband installed a pool!
For a day the water in it has heated up to a completely normal temperature.
At first children were sent there.

Three of our children and a neighbor's girl (next to my son).

We barely got the children out of the water. They did not want to go out.

P.S. In the pool there are already 4 trays. Tomorrow my husband promised that he would glue a fifth.
