Do you remember your 6th or 7th grade Science Class? yeah, me neither, but after some research in my "Old School Papers" I found out that we studied natural disasters, and one of them was tornadoes. First, a little information on a tornado:
"A tornado is a natural storm disaster created when a front of hot, humid air and a front of cool, dry air collide in the atmosphere. The warm air is pushed upward, which causes winds carrying water droplets to rotate into a vortex, speeding at up to 300 mph in the center. This spinning column of air and water droplets then begins to stretch between the earth and a convection cloud (made up of water droplets) to create a tornado. The water droplets form from the condensation of water vapor in the area within the funnel where there is low temperature and pressure. This makes the funnel visible to our eyes, because the large number of water droplets block out the sun's light, just like a thunder cloud." (www.haverford.edu)
This little experiment shows the physical properties of a tornado on a small scale.

To make a Bottled Tornado, you will need the following:
- two empty 2 or 3 litre bottles (cleaned)
- water
optional:
- a tornado tube
- ducktape
- washer
- lamp oil
- two empty 2 or 3 litre bottles (cleaned)
- water

it doesn't matter how much oil
Nice Instructable, I want to try this out.
Haha I just realized that bumpus made this because you replied to Killerj's comment.
+5/5 stars.

We use a hot nail to melt holes in the caps of two bottles, then hot-glue them top-to-top, sometimes with duct-tape reinforcement.
They're not as pretty as the manufactured tube, but it means I can make twenty bottled tornadoes for almost nothing.
We also occasionally add a little glitter to the water, and one child once added a small picture of a cow, as a tribute to the film Twister.
