| Video Discription | Experiments with water and air help children understand how and why real wonders and tricks happen! After all, the magic of the experiments is explained by physical phenomena. Homeschool kids with experiments. 1. POWERFUL TISSUE It's the surface tension of the water, which works magically. The water filled all the gaps in the tissue and blocked them, forming a thin layer called surface tension. 2. BATTLE OF WATER AND AIR When the neck of an upside-down bottle is in water, it doesn't come out of it. The pressure of the water column inside the bottle is balanced by the atmospheric pressure on the open surface of the water in the container. If the neck of the bottle is above the surface of the water, the pressure inside the bottle becomes greater than the atmospheric pressure and it pours out. 3. PING PONG BALL TRICK When we put the ball on the top of the bottle, it pushes all the extra water out of it. When we turn the bottle upside down, all the water stays inside. The pressure of the water inside the bottle is balanced by the atmospheric air pressure on the ball, which is kind of stuck to the neck of the bottle. Surface tension of water helps it do this. The water molecules are attracted to each other, closing the small opening between the ball and the neck of the bottle. 4. INVISIBLE POWER When you spin the bottle of water, the centrifugal force - the force that occurs when the object rotates - acts on them. Because of this, the water is pressed to the bottom of the container and does not splash out. If you let go of the rope during rotation, the bottle will fly up or sideways, depending on where it is at the moment. The same thing happens to the water inside - it heads in the opposite direction from the rope, but it is held by the bottle. 5. PAPER COVER The air pressure in the glass is lower than the atmospheric pressure. The pressure outside is greater, so the cardboard presses against the glass and prevents the water from spilling. 6. THE SECRET OF WATER The water does not pour out because of air pressure and surface tension. The air pressure inside the bottle is lower and the air pressure outside it is higher. Also, the water filled all of the tiny holes in the cheesecloth and held the entire volume of water in the bottle due to surface tension. 7. AIR PRESSURE TRICK Water flowing out of the glass and soaking the cloth lowers the air pressure inside it (if there is no space for air circulation between the glass and the lid). The glass is sort of "sucked" onto the smooth flat lid. But the atmospheric air pressure remains the same. This is what holds the lid under the glass sucker on the lid. 8. AIR PRESSURE HOLDS WEIGHT In order to hold heavy objects, it is necessary to lower the pressure inside the glass. In this case the atmospheric pressure will be able to hold some weight. When gases are heated, they expand. When they are cooled, they contract. When the candle goes out, the air inside the glass cools and compresses, sucking the water inside from the napkin. If no gap is left between the glass and the napkin, the air inside will be discharged and the atmospheric pressure will help lift the weight. ⇒ Check this simple experiment Cool baking soda experiment "Fizzy funny Trolls" https://youtu.be/oRKU5iObyB8 ✅ Subscribe to KITCHEN SCIENCE LAB and click the bell 🔔: https://www.youtube.com/channel/UCftqATvrsbewPIEbLabY4nA/?sub_confirmation=1 ✅ Instagram: https://www.instagram.com/for_curious_children/ ✅ Donate the channel: https://www.donationalerts.com/r/kitchensciencelab #waterexperiments #learnwithfun #KitchenScienceLab #kitchenscienceexperiment #airexperiments |
