Final answer:
To make a mini tornado with bottles, water, a washer, and tape, fill one bottle, stack the bottles with the washer in between, tape them securely, invert and swirl to create a vortex resembling a tornado.
Step-by-step explanation:
Creating a Tornado
To create a tornado using the given materials, you need two one-liter bottles, a washer that fits the mouth of the bottles, and strong tape like electrical or duct tape. Here's how to manipulate these items:
- Fill one of the bottles about two-thirds full of water.
- Place the washer on the mouth of the water-filled bottle.
- Now, take the second empty bottle and invert it, placing its mouth on the washer so that the two mouths are touching with the washer in between.
- Secure the two bottles together using the strong tape. Make sure the bond is watertight and the bottles are aligned straight.
- Turn the bottles so that the one with water is on top and give it a vigorous swirl in a circular motion as you turn it upside down. This action will create a vortex that looks like a miniature tornado as the water spirals down from the top bottle to the bottom one.
This experiment demonstrates the physics of rotational motion and vortex formation, similar to the dynamics of natural tornadoes.
