I am using this flat bottle:
I fixed a motor at the centre of one of the flat sides and attached an impeller. I thought this will create some kind of whirlpool effect but as you can guess, since the motor is horizontal, the water also rotated about a horizontal axis. But it did not create any much effects. I turned up the power but I was afraid my motor could not get any faster.
My question is: do you think if I install a more powerful and faster motor, it will eventually create a mini vortex/whirlpool? If you saw the picture, the width of bottle is only around 2cm so its not very taxing I think?
What I am originally trying to do is to create some kind of continuous cool effect in the bottle. I initially planned to do something like this lava lamp by using pump to continuously circulate water in oil instead of the alka seltzer but it ended up mixing the oil and water into a cloudy solution. Another option was to create bubbles but I don't like that as its very generic.
So is it possible to create horizontal whirlpool/vortex? Or is there any other cool effects you can suggest I can make?
