A small tube that has a great effect: Take two ordinary plastic drink bottles, fill one two thirds with water and then connect the two bottles with our Bottle Tornado tube. When you now turn the bottles upside-down, the water starts gurgling down, creating a large vortex (you might have to squeeze the lower bottle a bit to start the process)
If you add some dye, the tornado looks even more impressive.
Dimensions: 48 x 33mm
