Squeeze the bottle and the packet should sink to the bottom of the bottle. How the Trick Works. An air bubble is trapped inside a ketchup packet when it is sealed at the factory. If the bubble is big enough, it makes the packet float in water. Since water is heaver than air, there is more force pushing down on a cup with water in it than a cup without water in it, and so it is more likely to sink.

When the cup becomes more dense than water, it sinks. The cup would sink just as well if you filled it with rocks, lead, etc. For example, an empty bottle will float in a bathtub that is filled with water if the bottle is less dense than the water. However, as you start filling the bottle with water, its density increases and its buoyancy decreases.

Eventually, the bottle will sink if it is filled too full with water. Originally Answered: Will a glass bottle full of water float on water? Glass is denser than water, so the water volume it displaces weight less than it, and therefore the buoyancy is not enough to keep it floating. Similarly, an empty plastic bottle floats on water. However, when you fill it up with water, the bottle sinks. This is because it is unable to displace that much volume of water.

You will also notice that it is easier for an aluminium foil to float in water. The air pressure outside of the bottle is now greater than the pressure inside the bottle. As a result, the bottle is crushed inward. You must be logged in to post a comment. Phone: Email: [email protected]. Leave a Reply Want to join the discussion? Feel free to contribute!
