It is easier to remove air from a balloon because it is made of a flexible material that can contract as the air is removed, allowing the pressure inside to decrease. In contrast, a glass bottle is rigid and does not easily change shape, making it harder to create a vacuum inside to remove the air.
This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.
To remove the bottom of a glass bottle, you can use a glass cutter to score a line around the bottom, then apply hot and cold water to the score line to create a crack and separate the bottom from the rest of the bottle.

To remove a label from a glass bottle, you can soak the bottle in warm, soapy water to loosen the adhesive. Then, gently peel off the label using your fingers or a scraper. If any residue remains, you can use rubbing alcohol or a mixture of baking soda and oil to remove it.
Take a metal cylinder, and place a spring in the bottom (as a shock absorber). Inside the metal cylinder, sitting atop the spring is a glass bottle. Between the cylinder and the bottle (around the sides and the bottom of the glass bottle) is a vacuum. Both the vacuum and the glass serve as insulators for anything that is to be stored in the glass bottle. This means that, if you store something warm in the inner glass bottle, it will be very difficult for the heat to conduct through the glass AND the vacuum...and the material will stay warm. If you store something cold in the bottle, it will be very difficult for heat to conduct through the cylinder, the vacuum, and the glass...and the material will stay cold.
To remove old beer sediment from a bottle, gently pour the beer into a glass, leaving the sediment behind in the bottle. Avoid shaking the bottle to prevent the sediment from mixing back into the beer.
one way that you can fill a balloon with hydrogen is if you get a glass bottle and put a lot of crumpled up pieces of tin foil into it and then pour a toilet bowl cleaner called "The Works" into the glass bottle then pot a balloonover the opening.
You can effectively remove paint from a glass bottle by using a paint stripper or a mixture of baking soda and water to scrub the paint off. Make sure to wear gloves and work in a well-ventilated area for safety.
To effectively remove a sticker from a glass bottle, you can try soaking the bottle in warm, soapy water to loosen the adhesive. Then, gently scrape off the sticker using a plastic scraper or a cloth soaked in rubbing alcohol. Repeat as needed until the sticker is completely removed.
Grease the top of the bottle!
When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.
