The water in the swimming pool was freezing. It was as cold as the ice on the North Pole.
I hopped in the freezing pool, went under the water and got up so quick that I was almost out of the water in a flash. Everyone was in the pool was shivering because it was so very cold. Later on people started to swim because they got used to the water. The teacher taught us freestyle strokes and correct breathing techniques. After the swim, towards the end, the class got some free time so we could do anything we wanted to do like handstands and back flips but not bombing the pool.
