Meteorology Science Fair Project

Create a Tornado in a Bottle

Create a Tornado in a Bottle | Science Fair Projects | STEM Projects
Create a powerful vortex like a tornado in your own home! All you need is two pop bottles, duct tape, silicon caulking, water, and a drill.


The hypothesis is that a vortex will form when the two pop bottles are connected and the water is drained from one bottle to the other.

Method & Materials

You will need to drill a hole in the caps of two pop bottles, seal the caps together with silicon caulking, and attach the two bottles together with duct tape. Then fill one bottle with water and attach it to the other bottle. Finally, swirl the bottles in a few quick circles to create a vortex.
You will need two 2-litre pop bottles with caps, duct tape, silicon caulking, water, a drill, food colouring, and plastic confetti.


After completing the experiment, you will have created a powerful vortex like a tornado in your own home! This experiment is a great way to learn about the power of tornadoes and the science behind them.

Why do this project?

This science project is so interesting and unique because it allows you to create a powerful vortex like a tornado in your own home.

Also Consider

Experiment variations to consider include adding food colouring or plastic confetti to the water, or using a “Tornado Tube” adapter to connect the two pop bottles without drilling or gluing.
