    Look that video! Magnets can have incredible effects!

    Most ignore that such cool stuff exists. Science would be more popular if these gadgets was a bit more known...

    I'm surprised!

    I've shown that thing even to a lot of physics teachers and most didn't know that thing.

    If brain has a matter with knowing this, maybe would you be surprised too to learn how much of your friends doesn't have one! lol

    take care

    I have to agree with zelos anyone who has had experience with a magnet before knows what it is capable of... I mean sure its cool but everyone already knows about it.

    I am guessing you made this video since I saw your name in the credits. Ill have to show one of my friends who is a grade 6 teacher to show the kids in the class room. I am sure they would really enjoy it.
    whats the interval of 1/mower? lnmower... heh

    nice video.

    i presume the thing underneath is a magnet, but whats the spinning thing made from ?? where can i get me one of these ?
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    both are magnets the spinning part is done to keep the magnet from flipping so it becomes attractive instead of repulsive

    Leo - they are around £30-00 from the Science Museum, next time you are up the smoke, drop into their toyshop.

    The princilpe is simply a strong ring of north pole magnets, in the centre a weaker south pole, this causes a dip into which the gyro 'sits' - the little magnet is spun, precession forces prevent the 'top' from 'flipping' until it has slowed substantially.

    For some other interesting toys visit:- http://www.grand-illusions.com/acatalog/ - down the left side you will see the various categories, most have a video to accompany them so you can get an idea of what they look like.

    If you buy the "Levitron" - you will need patience to set it up, if the magnetic field is not exactly level the top will just slide off.

    Okay thanks, I shall keep my eye out for one

    Last time I went to the science museum I bought myself a bar if metal soap. It didnt work.

    I ordered one of these for my grandson, it arrived this morning, there are four variables! - levelling the table, the initial speed of rotation, the weight of the giro and finally the speed at which you raise the table - It comes with a set of weights from 0.1 to 2 grams in various sizes. It has taken about 2hours of patient work to set it up, now 1 in ten times I spin it and it will hover for about 5 seconds, about 1 in 50 times I can get it to hover for 30 seconds or so.

    First you learn to spin the giro (most times initially it just flips out of your hand in the very strong field. After you master this you raise the table and watch how fast it 'shoots' up in the air, from this you play with the weights until it gently lifts off, next it careers sideways, which is where you adjust the table. If it is at all 'unstable' ie 'wobbling' then it won't work. It took us about 3 hours to get this far, of the 5 people who have tried to spin this so far only 1 person has suceeded - but it does work and it is awesome to see!
