Fill one empty bottle partway with water, take a second, identical empty bottle and connect it neck-to neck with the other bottle. The are special connectors for doing this, but Duct Tape can work if you don't have one as long as you hold on to that part.
Once they are connected turn the whole thing upside down and briefly shake it in a circular motion. A "tornado" should form in a couple seconds.
it is a bottle shape
If you mean a hurricane in a bottle then yes, a hurricane in a bottle and a tornado in a bottle are the same thing. In shape, however, the vortex bears more resemblance to a tornado than a hurricane.
Both the tornado in bottle and a real tornado involve a vortex that strengthens via the principle of conservation of angular momentum.
It doesn't really. A tornado in a bottle provides amusement, but little else.
you spin the bottle fast and stop
Whirlpool
tell me the answer
Mainly scientists that study tornadoes or tornado watchers
by swirrling the bottle in circlesz causing a rotating funnel in the water
The amount of water and the temperature of the water and the angle the bottle was set in.
I think you should try there are many video showing how to make a tornado in a bottle. Do the experiment and add the marble in there and see what happen.
the water swirl and it goes to the another bottle at the edge and the air also
