<html> <p><strong>Experimenting with atmospheric pressure</strong></p> <p>We have already seen several homemade experiments of this type, but there are still some more interesting to demonstrate the effects that can be caused by the pressure of a gas, in this case, the pressure of the atmosphere with which we live. So we are going to see a simple but impressive<strong> experiment on atmospheric pressure</strong>, where we will put a glass of water upside down, and it will not fall. Let's see what we need.</p> <p><strong>Materials:</strong></p> <p><strong>* </strong>Glass cup.</p> <p><strong>* </strong>CD or DVD box.</p> <p><strong>Process:</strong></p> <p>First we must put water in the glass, almost to fill it, but leave it with approximately one centimeter less than the top level.</p> <p>Now take the CD or DVD box and disarm it. You will need the lid.</p> <p>Take the latter and place it on top of the glass. Press with your fingers and rotate everything, until leaving the glass in vertical position but with its bottom completely up.</p> <p>Carefully remove your fingers from the lid, and see what happens.</p> <p><img src="https://www.tutiempo.net/meteorologia/i/articulos/n4/Imagen9.jpg" width="728" height="410"/></p> <p><strong>¿How does the experiment work?</strong></p> <p>It is hard to think that the water will not fall. But like everything, it has a scientific explanation, in this case, a physical explanation.</p> <p>What happens is that when we turn the glass, the water does try to fall. The problem is that the pressure in the upper air chamber drops, because as we said, the water column tries to fall by its own weight.</p> <p>On the other side of the plastic lid we have atmospheric pressure, which presses on the entire surface of the lid, preventing it from falling.</p> <p>If for some reason air bubbles enter, this will cause the pressure inside the vessel to increase, and the outside pressure, which is atmospheric, can no longer "hold" the lid.</p> <p>In the following image you can see more clearly everything that is happening:</p> <p><img src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQA1P2m-Q-C-kM5d9mvBwVKeXUkydQB9lvdvKnFhwQXeoWsAw6S" width="255" height="198"/></p> </html>
