What experiments can you do with a water bottle?

What experiments can you do with a water bottle?

When you cover up the lid to the bottle, the water is pulling down but that air up in the top of the bottle is becoming a vacuum. That means “low pressure.” The air pressure outside the bottle is higher, so it actually tries to push into the bottle through the bottom hole. In doing so, it keeps the water in!

Why the water fall back to the bottom of the bottle?

Water evaporates, turns into a gas, and rises into the air. This collects water droplets at the top of the bottle, known as condensation, when gas turns back into water. When the water gets heavy enough, it falls back to the bottom of the bottle just how rain falls back to earth.

What happens if you put hot water in a plastic bottle?

Plastic water bottles are made from polyethylene terephthalate. Whenever a bottle is heated, the material releases the chemicals bisphenol and antimony, also known as BPA. There have been studies to suggest that this chemical can cause adverse health effects in children.

Can you make a cloud in a bottle?

When you pressurize the soda bottle by pumping air in, the air molecules collide with each other and warm the bottle. Releasing the pressure causes the water vapor to condense quickly, forming a cloud.

How do you make a tornado in a bottle without a tornado tube?

To make a fun tornado in a bottle, all you need is a plastic bottle and dish soap. Start by filling the bottle with water, leaving 2 inches of air at the top. Then, add 2 small squirts of dish soap. You can also pour in some food coloring or glitter to make a colorful tornado!

How do you make a cloud in a bottle experiment?

Make a Cloud in a Bottle

  1. Materials. Transparent glass jar.
  2. Form the water vapor. Fill a jar with 2 inches (5 cm) of warm water and stir.
  3. Form smoke particles. Ask an adult to light a match, blow it out and quickly drop it into the jar.
  4. Cool it.
  5. Watch the cloud appear.
  6. Make it disappear.
  7. The real deal.

What caused the plastic bottle to crush when it was placed in cold water?

As the air inside the bottle cools quickly, the air pressure drops quickly inside the bottle. Once the air pressure is lower inside the bottle and higher on the outside of the bottle the outside force of the air pressure pushes down on the bottle and collapses it.

What happens when bottled water is exposed to sunlight?

The safety of bottled water in the sun is quite stable for shorter periods. The 2014 study found over four weeks that as exposure lengthens, chemicals increase but level out before they become unsafe.

Is it OK to drink bottled water left overnight?

The water left overnight or for a long period of time in an open glass or container is home to numerous bacterias and is not safe for drinking. You never know how much dust, debris, and other small microscopic particles might have passed into that glass. Water left in a bottle for a long time is not safe to drink.

How do you make a cloud in a bottle?

Can you make a tornado in a water bottle?

Seal the container tightly. Move the bottle rapidly in a circular motion. After a few seconds, you should see the water begin swirling. Stop, and watch your tornado!

How do you make a thunderstorm in a bottle?

Fill your glass or jar nearly to the top with tap water. Make a great, big rain cloud of shaving cream on top of the water. Drip the diluted food coloring onto your cloud and watch the rainstorm of color. Note: Color may take a minute or more to seep through your cloud.

How do you make fog in a water bottle?

How to Make Fog in a Bottle

  1. Fill a jar or bottle with HOT, HOT water for 60 seconds.
  2. Pour out most of the water and then place a plastic bag with ice cubes over the top.
  3. Fog will start to form inside the bottle. And here’s the interesting part…

What causes the plastic bottle to expand?

Temperature effect Filling and capping products such as sauces at an elevated temperature (such as during hot filling of certain products) causes the air inside the container to expand.

Why do water bottles pop at night?

The “pop” you hear is caused by a sudden change in air pressure. When you release the cap, the higher-pressure air inside the bottle rushes out into the lower-pressure air inside the room.
