1 Experiment Explanation: To do this experiment you need to heat the bottle too much... I am using hot water to do this...this is the main reason... actually bottle is heated for that inside the bottle chamber creates a vacuum....and for the atmospheric pressure water suck... 2 Experiment Explanation: For the heat, the vacuum created inside the glass...and that's why dish sucks by glass 3 Experiment Explanation: Nail polish consists of alcohol which is highly flammable... 4 Experiment Explanation: When you pull back on the plunger, you increase the amount of volume inside the syringe. However, the contents of the syringe can't change because you have sealed it. The air inside the tube acts as gases do and the molecules spread out to fill the whole space. The atmospheric pressure inside the syringe drops, creating a partial vacuum. The vapor pressure of the water becomes high enough compared to the atmospheric pressure that the water molecules can easily pass from the liquid phase into the vapor phase. This is boiling. You also need to know…The boiling point of water or any other liquid depends on vapor pressure. As you lower the pressure, the boiling point of the water drops. You can see this if you compare the boiling point of water at sea level with the boiling point of water on a mountain. The water on the mountain boils at a lower temperature because of lower the pressure. This is the reason for the experiment. 5 Experiment Explanation: When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. Due to this carbon dioxide balloon become inflate. If you like this video then please share, with your friends and watch our latest video for more science experiments.

Because as he use hot water in it the air escapes out from bottle which lowers the pressure and as he take it to cold water the pressure outside bottle become greater the inside bottle so pressure outside pushes water up
Bhaiya me nu kehra matlab maja hi aaja thari video si dekh ke nu lage jese raat me suraj aagiya maja hi aagya thankyou bhai agar achha laga ho to like kar do
Sir tomorrow is my online science exhibition. I study in class 8th . I want to do your 2nd experiment. But I can't understand that why I should use wet napkin?? What is it's role in this experiment?? Please tell me sir🙏🙏🙏
This is an example of Low air pressure Vacuum Experiment...due to heat vacuum created inside the bottle and for atmospheric pressure water goes inside the bottle
