whirl in a glass of water?

Postby Johnny-M » Jan 3rd, '09, 00:45



It just came to my mind when I was thinking of the PK putty for a trick..

I have no idea how it would be possible or if it could be done, but I´m thinking of putting a glass on a table, pour some water in it, move my hand arround it without touching it, and get the water inside the glass to spin and form some kind of whirl in the glass.

that would surely look like "real" magic ;)
What do you think??

this will magnetize your water which might enable some impressive feats

Unfortunately, sticking a glass of water in the middle of some magnets won't magnetise it.

There's a stunning amount of junk science on that page, and site...

On the other hand, this might be a source for cheap, powerful magnets, so it's not all bad :)

Your reality, sir, is lies and balderdash, and I'm delighted to say that I have no grasp of it whatsoever.

It's showing one of these:

Although the illusion is pretty good, so it's worth thinking about.

I'm no scientist, but there are some very dubious-sounding claims there; I noticed a distinct lack of independent links to support their claims.

In reply to Johnny-M, I remember reading about this very thing somewhere. But I just can't seem to recall where. I know that's of no use to you (sorry) but I will be back if I have a sudden moment of total recall.

I buy my magnets here; http://www.neotexx.de/ they have really high quality and have very fair prices, (PK ring (neodym) for 9.- Euro)

OK what about this, I think to remember an old household remedy for Iron shortage is to boil a bunch of nails and drink it, I don´t think that would increase the Iron in the water enough to get it so spin, but maybe something in that direction to increase the iron amount in water without making it visibly.

The Magnetic stirrer is really something to think about.. I might get my (non-existent) DIY skills to work!

well from what i understand as long as the water remained on the coaster it would be magnetized but if you removed it from the magnet that would cease if the field is stong enough to make it spin is questionable but maybe a combination of that and the nail thing might work.


this illusion sounds quite good

in my mind im now thinking of parting bowls of water moses style and getting all biblical with magic


maybe thats cos its late and im watching dogma


i remember reading a science project ages ago where some kid tried to test if magnetic water had any positive affect and there was no evidence but im pretty sure the water was magnetized

I don't think you'll find a solution (hah!) involving actually magnetising the water.

Magnetism is all about aligning the domains within a substance. For a substance to be magnetised it has to be ferromagnetic, that is to say that the domains have to be able to align freely with the magnetic field and stay put once they're there.

Short of having a very strong and continuous field, far outside practical scales, you're not going to see this in a liquid, especially water. Ferromagnetic substances are almost always solid, for example iron.

Fun fact, water is diamagnetic, so it is actually very very minutely repelled when there is an interaction with a magnetic field.


A concealed stirring device, possibly one that was activated from below with a magnet, as in the magnetic stirrers in the video and in labs, might actually work.


(For all it doesn't matter, my degree was in Physics with Satellite Technology)

I found this,

http://chemistry.about.com/od/demonstra ... magnet.htm

but liquid ferromagnets are nothing new, and it doesn´t look like water at all..
maaaaaybe mixing it with coca cola, in a new can, open the can in front of the spectator and pour out the cocacola into a glass and do the trick?? still credibly??
