Water will start spiraling into the lower bottle in the form of a tornado! The kids loved watching the tornado spin round and round in the bottle.

How to tie a tite had a little trouble getting it started at first, but after a few tries, they were experts at forming the tornado! We did start off the experiment on the wrong foot.

We used a washer that had a very small opening, and no matter how much we twirled the bottle, we could not get the tornado to form. Since we used crazy glue, we could not separate the bottles from the washer and had to ditch the whole set up.

Thankfully, our second try was successful! You might have noticed that when you first turn the bottles over, hardly any water drips from the top to the bottom bottle. When the water is not spinning, the surface tension across the small hole in the washer prevents the water from dripping. You can try the experiment without the washer and observe what happens. When you twirl the bottle in circles, the water starts rotating and forms a vortex that looks like a tornado. This is due to the centripetal force, or the inward-facing force pulling the water toward the center of its circular path.

The hole in the vortex breaks the surface tension and allows air to flow from the lower bottle to the top bottle. I have lost count of how many times my kids spun the bottle to create the tornado.

Part 1 of Fill a plastic bottle with water. Leave two inches of air at the top of the bottle. The size of the bottle doesn't matter — but the bigger the bottle, the bigger the tornado. The bigger the tornado, the easier it will be to observe the effects on the water.

Try experimenting with more or less water. Record whether the amount of water has any effect on the size and speed of the tornado. Add dish soap. Two squirts from a bottle of concentrated soap will do. You can also use oil, or anything hydrophobic that repels water. Do not use laundry detergent: it is designed to interact differently with water than dish soap.

See if a particular brand works better than another, or if more or less soap makes a difference. Add a pinch of glitter. This step is optional, but it may make it easier to see the tornado in action.

Alternately, add food coloring for flair. If you're using a large bottle, try putting a few plastic Monopoly houses into the water to simulate the "houses" that are being picked up the tornado. Seal the bottle. If you are making a one-bottle tornado, you just need to twist the cap and seal it shut.

If you are making a two-bottle tornado, you'll need to find a watertight way to fix the openings so that they face one another. Try using superglue, caulk, duct tape, or a large rubber band. Part 2 of Make sure that the bottle is sealed. The trick won't work well unless the container is completely airtight. Test the cap with your hand. Spin the bottle. Hold it by the top or the bottom, and use your wrist to shake the water in a loose circular vortex.

After a few seconds of spinning, you should see the water begin to swirl in the center. This is your "tornado. How does the glitter interact with the tornado? Try spinning the bottle slower or faster. Try spinning it upside down.

Observe whether changing the spin pattern has any effect on how the tornado looks. Learn why the water is spinning. It is responding to "centripetal force" — an inward-facing force that pulls an object or liquid toward the center of its circular path. Part 3 of Make sure that the two bottles are attached at the mouth.

The connection should be airtight and watertight. Set the bottles upright so that the bottom of the full bottle is sitting on the ground or table, and the bottom of the empty bottle is sticking straight up into the air. Be sure to leave an inch or two of air at the top of the "full" bottle. Flip the bottles upside-down. Think of it like the motion of flipping an hourglass. The bottom bottle should now be empty of water, and the top bottle should be full of water.

Hold the bottles for support — the contraption will be top-heavy! Watch the water trickle down. The air pressure in the now-top bottle is lower than the air pressure in the now-bottom bottle, so there should not be much water flowing between the mouths of the bottles.

Swirl the water-filled bottle in circles. If you gently spin the water-filled bottle on top, water should begin to pour again. This should create a vortex or "tornado" in the center of the water-filled bottle as the liquid flows from a space of low pressure to a space of high pressure. You can seal it with a glue gun.

Not Helpful 26 Helpful Yes, you can use different sized bottles. The size of the bottle doesn't matter, just make sure you have the right amount of water in it.

Not Helpful 20 Helpful You can use clear glue with water and glitter. Pour glue into the water bottle with water, and add some glitter. Not Helpful 35 Helpful
