Wonder still exists?

Last Sunday, a very hot day, we spent at the pool again. Marisol who had a drowning-accident when she was young is afraid of deep water because of that. I proposed her to make an attempt. But before make a mental training. I asked her to close her eyes and pretend in her main that she was swimming and really feel how she was floating. She did that and then she made a try in the pool. The result you can see in the next video. I was really surprised.
