If you press the stopper down farther, the volume inside the bottle decreases. As a result, the pressure inside the bottle increases because the gas particles inside the bottle are now more compressed due to the reduced volume.
Pressing the stopper down farther would decrease the volume inside the bottle and increase the pressure. This is because the volume and pressure of a gas are inversely related according to Boyle's Law.
With a few exceptions (notably melting ice) objects expand when heated. If you run hot water on a bottle neck, the heat is applied directly to the bottle and only indirectly to the stopper inside the bottle, so the bottle heats first, and thereby expands sooner than the stopper does. An expanded bottle will exert less pressure on the stopper.
Blowing into a water bottle creates air pressure inside the bottle, which pushes the water out. This can create a bubbly or foamy effect as the air mixes with the water.
When a soda bottle is shaken vigorously, the pressure inside the bottle increases. This is because the shaking causes the carbon dioxide gas in the soda to become more agitated and create more pressure.
When the water in the bottle is cooled, it contracts and creates a lower pressure inside the bottle. The higher atmospheric pressure outside the bottle pushes the water up through the straw to equalize the pressure, causing the water level in the straw to rise.
Increasing the pressure on the stopper in a bottle of water will compress the air inside, which in turn increases the pressure. This will cause the pressure inside the bottle to rise. Conversely, releasing the stopper will decrease the pressure inside the bottle as the air expands.

The pressure will slightly increase.

what happens if you squeeze a bottle with a balloon
The reagent bottle is not used for dropping, having only a common stopper.
The 'operator' fills the bottle with water, then pumps air into it - creating pressure. When the stopper is released, the air pressure forces the water out of the narrow opening in the bottle's neck - creating a stream powerful enough to launch the rocket into the air.
To make a potion bottle, you can start by finding a glass bottle with a cork or stopper. Clean the bottle thoroughly and let it dry. Then, you can decorate the bottle with symbols or labels to make it look like a potion bottle. Fill the bottle with colored liquid or glitter for a magical effect. Finally, seal the bottle with the cork or stopper securely.
