- Begin by having kids mix a tiny amount of glowing paint with very warm water until the paint is dissolved. Set this aside.
- Have kids fill an empty glass jar with water, leaving about an inch of room left at the top.
- Then, have them add a few drops of the paint- water mixture to the jar along with a squirt of dish soap and mix. An eye dropper or old medicine dropper works really well for this
- Seal the jar, and the fun can begin!
Kids will have a blast swirling the jar to create their glowing tornado
Rosie and Jewel loved experimenting with how they swirled the jar to see who could form the biggest vortex
After a bit of trial and error we found that the best tornado was produced when the jar was held and then shaken rapidly in a circular motion
My girls had lots of fun exploring with their glowing tornadoes, and of course we ended up making several- they just had to make a variety of colors!
Making a glowing tornado?
That’s just plain fun!
How does the tornado form in the jar?
- As you twist the jar the water inside is pulled due to gravity and friction. The fluid toward the inside of the jar takes longer to be pulled, but eventually both the glass jar and the fluid are spinning as you rotate the bottle. When you stop rotating the jar the fluid inside keeps spinning, creatng a vortex just like a tornado. Read more on how the tornado forms inside the jar.
- The vortex created in the jar is created in a similar way to how a tornado is formed in nature. Here is a step-by-step description of how tornadoes form if you are interested in diving further into the science behind this experiment.
