Love playing with this. It is fascinating to watch. When you pick it up it’s hard to put down. So much fun. I find that the adults want to play with it and take it from the kids!!!! Great gift!!
Very fun to play with and the magnet is excellent. The blue doesn’t really stain the water unlike reviews of other colors I’ve read. Great choice.
exactly as expected.
Very cool gadget. The flow of the ferrofluid is very soothing to watch. The unit is quite a bit smaller than I expected, but then again I did not pay attention to the dimensions in the description. Also, I wish there was a continent place to store the magnetic "wand".
Fascinating device. Great for stress relief. Definitely a 5 out of 5.
