Well, no big deal. The density is not so much that we are unable to swim, but it is enough to be noticed. The point is that this layer of hot water, which slides over the vast majority of cold water (which is 90% of water), it is called "Termoclima” or the Thermocline. (Make a move funny and great for children to repeat two or three times. Movement helps remember the name).
ASSISTANT: A big applause for everyone!
