Tornado in a Bottle: Easiest DIY Science Lesson EVER!

The tornado in a bottle is seriously the easiest homemade science lesson–even science TOY if you will–that you will ever make!  We have had so much fun with this simple DIY activity!

I saw this pin on Pinterest and knew we’d have fun with it!  So a big thank you goes out to EllieMoon for her blog post, Tornado in a Jar DIY, which inspired us!

Materials Needed:
*a clean bottle or jar
*water
*dish soap

Could it get any simpler?

Directions:
I have been saving the kids’ vitamin bottles and decided that one of those would be perfect since it has a child-proof lid.  No need in getting soapy water all over the house if it can be avoided, right?  The bottle is also thick plastic, so I don’t have to worry about it breaking into a thousand shards of super sharp glass should the kids drop it while shaking!

I put the water in the bottle and let the kids squeeze in some dish soap.  We used Seventh Generation dish soap, but anything should work.  I screwed the cap on and made sure the bottle was watertight.  It was! 🙂

So, here’s our tornado in a bottle!  Please note: it is very hard to shake a jar, pick up your camera, get it to focus, and snap a pic before the little teeny tornado vanishes.  The tornadoes we create are much cooler than I was able to actually capture in the photos since I was working alone during nap time.

We’ve been keeping the “tornado in a bottle” on our kitchen table.  It’s at the right eye-level for the kids there, and I’ll shake it up once or twice while we’re eating for us all to enjoy.

You really can shake it all different ways to create a tornado.  That in itself is kind of a fun experiment.  It can take a little bit of practice to get the hang of it at first.  My method is to hold the bottle upright and make a motion like I’m stirring a big bowl with a wooden spoon, if that makes sense.  Keep trying until you get a swirling tornado!  Who can make a tornado that lasts the longest?

I think it’d be fun to experiment with different sizes of bottles to see which make the best tornadoes!  You could also try adding some food coloring, glitter, grass, or little objects like Monopoly houses to the water/soap mix for some additional experimentation!

Okay, so there you have it.  Go use up something in your fridge, wash the jar or bottle, and peel the label.  That’ll be the hardest part of this really fun science toy! 🙂
