tip from experience: if you place a washer between the two bottle openings, you will get "better" tornadoes. The outside diameter of the washer should be the exact outside diameter of the mouths of the bottles. washers this size usually have a hole with the diameter of about a pencil. (roughly 9mm) It doesn't matter whether you use rubber or metal washers. This example:http://1.bp.blogspot.com/_81Nc_4nc1kQ/SXfm9uQ5F-I/AAAAAAAACNA/jRuxIE6_mV4/s400/BILD3120.JPG shows a rubber plumbing washer. I added this to the ones I have made because I noticed on the storebought tornado makers always had a smaller opening between the bottles for the water to flow through.

it's true. i put green food coloring in it. it does look better.

acctualy, that not how they form.first, its a spinning tube laying horizontal (i forgot the name, but i learned it). hot air rising lifts the tube up. it connects to thunder clouds (yes, a tornado is part of a thunder storm). as the storm gets stronger, so does the tornado. also, if you add food coloring to the water 1. you can see it better 2. it looks cooler! :)

heres a harder but more efficiant way to join the necks together. use a drill to put a hole half as large as tha cap. do this in the center. then, use super glue/hot glue to join them together. make 1 - 3 circles of clue around the hole. press together. now, if you need to change the water, just unscrew the cap and refill.
