CMS Magnetics® 3-pc. Magnet Set for Levitation Project, OD 115mm x ID 45mm x 20mm - 2 Piece Bottom Magnets and One Piece Top Magnet

I highly recommend this magnets for many applications related to magnets!!

The magnets are fine. However they ARE advertised as a levitation set. In this they fail pretty spectacularly. There are ZERO instructions whatsoever on how to accomplish any kind of levitation at all. You can watch youtube videos on setup for a spinning top, but it is extremely finicky. I kind of expected a magnetics company to have a card or something which tells you the optimum distance to do the levitating top spinner, how much weight to add to the small magnet, etc.Some kind of setup hints to get you going. Having a small piece of plexiglass and some brass washers for weights would have made the set at least theoretically functional. As it is, its basically useless unless you want to dediate a lot of time to finding non-ferrous, balanced, correct sized weights, and piddling with it to get it to work.

Nice building material for a science project

Super attractive.

Just like the other reviewer (Mike P) observed, this came with no instructions or the required parts to make it complete to achieve the levitation like it's being marketed as.
