if your refering to a bottle you fill a giant bowl bigger than the bottle then you put the bottle under the surface then do the same to the cap whilevthe bottle is still under the liquesd and close it with both with the bottle and cap under the surface close it and tada!
Bubbles in your water bottle are likely caused by air getting trapped in the water when you fill it up or by carbonation in the water.
The air in the balloon will have a difficult time expanding to fill the bottle because the bottle is already filled with air at atmospheric pressure, which creates resistance. The pressure inside the balloon needs to overcome the pressure inside the bottle in order for the balloon to expand and fill the bottle.
yes because air can spread out.
Because the volume of air gets less as you fill it - making a higher sound.
Fill it with steam and quickly close the water bottle. You want the bottle to be filled with steam. Next, put it in the freezer. The steam will turn into liquid and so there won't be any air (there still some air.)
A 1.5 liter plastic bottle contains approximately 1.5 liters (1500 milliliters) of air when empty. When you fill the bottle with water, the volume of air contained within the bottle will vary depending on the amount of water you add.
A simple spirometer can be made using a large plastic bottle, a straw, and a water source. Cut the bottom off the bottle and fill it partially with water, then insert the straw into the bottle without letting it touch the water. As you exhale into the straw, the air will displace the water, allowing you to measure the volume of air expelled. Ensure the setup is airtight to get accurate readings.
You can use a scuba tank, but that is it.
When the air is removed from a bottle, the external air pressure becomes greater than the pressure inside the bottle, causing the bottle to collapse. This is because the air pressure on the outside is strong enough to compress the bottle's walls, leading to its collapse without the internal pressure to counterbalance it.
To put an egg inside a bottle without touching it, you can create a vacuum by heating the air inside the bottle before placing the egg on top. As the air cools, it will contract, creating a lower pressure inside the bottle that will suck the egg inside.
Yes you can if all conditions were perfect. By that I mean that the bottle would have to be a near perfect vacuum by sucking out the air from the bottle with the straw. The vacated air from the bottle would be replaced by the baloon stretching to fill the space left by the air. You would have no need to blow into the baloon as the vacuum would do the work for you.
Alphy gum does not stick in its bottle because it is coated with an anti-adhesion agent that prevents the gum from sticking to the sides of the bottle. This helps in easy dispensing of the gum without it getting stuck.
