The video discusses several interesting experiments and demonstrations:
1. The first experiment involves filling a bottle with hot water and placing a piece of ice on the top. The ice cools the top part of the bottle, causing the air in this part to compress and the pressure in the bottle to drop. This lower pressure causes the water to boil at lower temperatures.
2. The second experiment involves using a magnet to make a grape fly away. The presenter suggests that the sweetness of the grape might be causing this effect.
3. The third experiment uses a leaf, a small tray of water, and a ballpoint pen to create a "motorboat" that moves through the water, spraying ink.
4. The fourth experiment involves rubbing a plastic comb on a synthetic fabric to accumulate static electricity. This charge can attract various objects and even tap water.
5. The fifth experiment involves pouring raisins into a container of sparkling water. The raisins start to float and move up and down as if they were boiling.
6. The sixth experiment involves making a homemade version of fish caviar. This involves heating fruit juice, adding a thickener, and then pouring vegetable oil into a ball. Each drop of oil transforms into a ball and falls to the bottom of the container.
7. The seventh experiment involves using a bottle of sewer pipe cleaner, kitchen foil, and a regular ball to create a flying ball. The presenter warns that this experiment is dangerous due to the heat produced by the reaction and the explosiveness of the gas released.
8. The final experiment involves using a homemade pasta maker and a photo of cookies. The photo is cut into strips, which are then rearranged and glued back together to create new images. The presenter suggests that this could be used to manipulate images and create multiple versions of a single photo.
1. The video includes a demonstration of a physics experiment where hot water is poured into a bottle with ice on top. The ice cools the top part of the bottle, causing the air in this part to compress and the pressure in the bottle to drop. This, in turn, causes the water to boil at lower temperatures .
2. The experiment also includes a demonstration of the peculiarity of ice, where two pieces of ice pressed together stick due to a gluing force .
3. The video also discusses an experiment where a magnet is used to make a long stick with the ends of two grapes balance. When the magnet is brought close to the grapes without touching them, they begin to push off and fly away .
4. The video includes a demonstration of an experiment where a leaf is placed in a tray of water, and ink from a ballpoint pen is dripped onto the edge of a groove cut into the leaf. The leaf appears to move through the water like a motorboat, spewing ink from its tail .
5. The video also includes a demonstration of an experiment where a plastic comb is rubbed on synthetic fabric, causing the plastic to accumulate a static electric charge. This charge can attract various objects, including tap water .
6. The video includes a demonstration of an experiment where raisins are poured into a container with sparkling water. The raisins begin to fly up and down in the jar, as if they were boiling in the liquid .
7. The video also includes a demonstration of an experiment where a homemade device is used to cut a photo of cookies into many strips of the same size, creating two new photos .
