Tornado in a Bottle : Best Weather Science Activity Tornado in a Bottle - Learn to make a water vortex using swirling motion of water inside a bottle. How vacuum created by swirling motion creates a air pathway.
What is the tornado in the bottle experiment?
The “tornado” we see in the bottle in this experiment is really a vortex. The vortex is created when the liquid moves in a circular motion around a counterpoint. Gravity pulls the liquid down while air rises through the center of the vortex.
Why does Glitter in a water bottle make a tornado?
The water in the bottle is responding to centripetal force, a force that acts on a body moving in a circular motion. The motion is directed toward the center, which is also referred to as the vortex. This is what catches the glitter and makes it move. Have your child do variations on the experiment, and note whether they make a similar tornado.
How to teach kids about tornadoes in the classroom?
Teach them about the tornado and weather. Finally, ask them to connect two bottles and connect them with the connector to see the tornado effect. You can begin with the same lesson plan but can move forward in detail as these kids can summarize and make a report about their experience.
How do you make a tornado with a water bottle?
The water starts to go to the bottom bottle slowly while “glugs” of air come up. 6. Rotate the bottle, so the water is once again in the top bottle, then rotate it in a tight, clockwise circular motion. As you rotate the bottle a tornado should form as the water moves into the lower bottle.
What is the purpose of a tornado in a jar?
When you spin the water in the jar, it creates a vortex in the center. As the water spins, centripetal force causes the water to spin around that vortex making a mini tornado. Hurricanes have a vortex, too!
What is the conclusion of a tornado in a bottle?
Conclusions. Tornadoes are fast, violent swirling winds. In this experiment, the spinning of the bottles caused the water to take the shape of a tornado. The hole in the bottle allowed for the appearance of the tornado's tail - the most dangerous part of the tornado.
What are variables for tornado in a bottle experiment?
Turn a water filled bottle upside down. Hold the bottle vertical over a container to catch the water coming out of the bottle. When the water leaves the bottle an empty space is left at the top.
How is a tornado in a bottle like a real tornado?
When you spin the bottle in a circular motion it creates a water vortex that looks like a tornado. The water spins around the center of the vortex because of centripetal force. Centripetal force is any force that causes an object (in this case water) to move in a circular path.
What is a hypothesis for a tornado?
The hypothesis relates to an important component in tornado formation: the mixing of warm air on the surface and cold air in the upper atmosphere. When these different air flows are mixed together in a stormy environment with specific convective pressures, they can spiral together to create a tornado.
How do you make a tornado in a jar experiment?

How tornadoes are formed?
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction.
What safety measures should be observed during a tornado?
Go to the basement or an inside room without windows on the lowest floor (bathroom, closet, center hallway). If possible, avoid sheltering in any room with windows. For added protection get under something sturdy (a heavy table or workbench). Cover your body with a blanket, sleeping bag or mattress.

What is a tornado warning for kids?
Here are some notes on what to say:#N#“A tornado is a funnel cloud that can form during a severe thunderstorm. It produces high winds and can cause lots of destruction, but they are also very rare. If a tornado warning is issued while we are at home, we will hide together in the pantry. This is our innermost room in the house with no windows.”
What experiment did we use soda bottles for?
In this month’s STEAM Experiment for Kids, we’re reusing the empty soda bottles from the Soda Geyser Experiment last month to make a tornado in a bottle!
Why do water and air enter and exit a bottle?
The formation of the vortex makes it easier for the air to enter the top bottle and water to exit into the bottom bottle . The air comes up through the hole in the middle of the vortex and the water pours out around the edges of the bottle opening. If you don’t have a vortex, the air and water have to take turns entering and exiting the bottle making bubbles and moving much slower.
