To give my son the closest glimpse of a twister that I hope he’ll ever get, we decided to make our own tornado in a bottle out of two, 2-liter plastic soda bottles. This is a pretty popular science project and after doing it, we know why: it’s SO cool!
Simply fill one of the bottles two-thirds full with water. Add food coloring if desired. Place the second, empty bottle upside down atop the first and apply duct tape liberally to the neck of the bottles. Expect the bottles to leak some.
Once taped, flip the bottles and swirl them in a circular motion. Watch the water spiral from the top bottle to the bottom bottle in a tornado shape. (Even little brother thought this was awesome!)
After we finished, we read Charles and Debra Ghigna’s Step-Into-Reading fiction book Barn Storm. In this book, a twister moves farm animals to unexpected new homes. The cows now sleep in the children’s bedroom at night. Super silly!
Finally, my son watched a short montage of video footage of tornados on WeatherWizKids.com, the site with the tornado-in-a-bottle instructions we used.
Our conclusion … tornadoes are cool to make and cool to watch on video – but NOT so cool to experience.
