Description

Gravity pulls water from the top bottle down into the bottom bottle. When you swirl the water, it rotates as it falls down. The water spiraling down from the top bottle into the bottom one moves faster and faster as it falls. Compare the speed at which a spun bottle and a still bottle will empty, discuss the reasons for any differences. Teacher Tip: The better and more water-tight the seal, the more successful the vortex will be. You may need to lend a hand at this stage.

Pressure difference and rotating speed: The pressure diff refers to the air pressure at the center of the funnel compared to the surrounding air. Most tornadoes have a calm center with low air pressure. This low pressure area draws in higher pressure air and forms the vortex that leads to a tornado. A bigger difference in pressure makes a bigger tornado with faster winds. That's why increasing the difference in pressure also increases the wind speed in this simulation. To use the “tornado maker,” turn it over so that the bottle with the water is on top. Swirl the top bottle in a circular motion and watch carefully to find the column of air form at the core of your water vortex. Funnel width: The part of the tornado we can see is the funnel, which is the tube that extends from the cloud to the ground. The effects of the wind from the tornado are much bigger than just the funnel, though.Place the second (empty) bottle upside down above the first (filled bottle). Carefully line up the two mouths and tape them together using duct tape, taking care to create a water tight seal. Seal further with electrical tape.

Fill one of the bottles 2/3 full of water. Add glitter and food colouring. This will make the water movement easier to see. All tornadoes, and most other severe local windstorms, are assigned a single number from the Enhanced Fujita Scale according to the most intense damage caused by the storm. A vortex is a swirling mass of fluid (a liquid or a gas). We see vortices in nature when we see phenomena like whirlwinds, tornadoes and whirlpools, but you can create your very own vortex using a simple set-up of two pop bottles and a washer.In this tornado simulator, the fastest wind speed is 220 miles per hour, but tornadoes' wind speeds can be as high as 300 miles per hour. The faster a fluid moves, the lower its internal pressure (this is called Bernoulli's Principle, named after the scientist who discovered it). So, as the water in the top bottle spirals inward and down, getting faster and faster, its pressure decreases.
