This is my 1st attempt to produce an instructable, I'm going to explain you how to build a system to levitate a magnetic top. It seems there is a commercial toy like that and now you'll be able to made it on your own. I've avoided inserting theory inside this instructable, just remember the system is based on magnetism and angular momentum (see also bibliography at the end). The system is sensitive to dimensions and weights and I've wasted a lot of time to reproduce it, so if you want to build it up try to follow my hints, probably you can get the same results with a different model but prepare yourself to be patient.

I must start looking for bits and pieces to build one of these.
I'm happy you like it, belive me its incredible when you see the top flying

There are some odd language constructions, but they appear to me rather similar to some of the Italian/English translation issues my experimental collaborators occasionally have.
I'm improving the instructable. I've made a new shorter you tube video (less boring).
Unfortunately I'm not able to add it anymore to the instructable. I don't know why. when I push the "embedded video" button (in the edit menu) it appears an empty space where to paste the code coming from the you tube video, but when I push the "Ok" button nothing happen.
If I use firefox a "javascript:void(0)" mesaage appears in the bottom left window,
if I use Internet Explorer "Errore nella visualizzazione della pagina"
Can you help me
The "javascript:void(0)" you see in your browser frame is normal; that's because the OK button is not a hyperlink, but rather a JavaScript action.
The site has been doing some software updates over the past couple of days. It's possible that they touched the code which handles the video embedding and broke it.
If you are still seeing this problem, would you mind posting a bug report?
a) removed the old code from the instructable (actually is just a frame with the "flash" tag inside) and added the new code. As I told this doesn't work.
b) I left the "original instructable step" with inside the old video (which is working) and I added a new step with the new video. Same problem as a)
c) I've repeated step a) and b) after rebooting my PC. Same results.
d) I've made step a) but from my laptop and now it works. As I can see there are some different windows update still pending on my laptop. Currently, instead, my PC is fully updated.
For the contests, you should click on that link, and see what sorts of contests are currently running. The only one active right now is for homemade soup; I don't think this qualifies :-)
If you are interested in writing up other projects that you create, you should keep an eye on the list of contests, and also look at the discussion forums for announcements of upcoming contests, so that you can plan for them.
Good luck, and welcome to Instructables!
Bye and thanks
In your final step, where you want to have a video, it would be better if you created an account on YouTube, or Vimeo, or one of the other video-streaming sites. Upload your video file there, then use that site's "embed code" to attach the video. Instructables doesn't have the bandwidth to support streaming video directly.
