Magnetism and gravty, nice effect, followed the link & had a look at the gallery, #14 adds surface tension.I put #22 in my 1st comment but when I went back to the gallery pics #22 had changed to #14, spooky, must be another force :)
Huge magnet. Don't think giant horseshoe magnets are still sold because tiny NiFeB magnets from China are much more powerful.
