Tornados! in a bottle

You will need:

- 2 empty 2 Liter bottles (clear works better, but green will do)
water
- plastic vortex connector (sold at teacher stores or online)
if you can't find the vortex connecter, you can make this with a drill, caulk and duct tape (you can make anything with duct tape!)
- food coloring *
- glitter *
- dish soap

* optional, but fun



How to do it:

- empty (aka drink) the plastic bottles and rinse them out
- remove the labels
- fill one bottle 2/3 full of water
- put in glitter and food coloring (and/or even a drop of dish soap for bubble effect)
- screw the plastic vortex thingy on the bottle and then screw the other bottle into the top

Ok, you've got your bottles ready to make your tornado!

Tip the bottles over so that the bottle with water is on top. Spin the bottle to create a cyclone or tornado!

** To make this without the plastic vortex connector: simply drill a hole in the center of each bottle lid. Put the lids back on the bottles (after filling one with water) Put a dab of caulking on the lids and connect them. Then secure them together with a lot of duct tape :)  I personally think it's easier to purchase the plastic thingy.
