Diviertete Con Aire (Diverticiencia/ Fun Science) - Tapa blanda

Sinopsis

We are going to assume that you are playing at home with a friend and that, suddenly, both of you are thirsty. After each one is finished until the last drop of water, you ask him if the glasses are empty or full. Completely empty! He answers something angry, but you reassure him that they are totally full of air! To prove it, you take a tequila glass, put a piece of paper in it, press it against the bottom and insert it face down into a transparent container that has a little more than half the water. You leave the glass submerged about 20 minutes. Then you remove it, take out the paper and ... your friend discovers, very impressed, that it is dry. You explain that the water could not wet the paper because the glass is full of air, and that it always occupies a place in space, because you already read Have fun with air.
