It really is cool — it is quite blue (I worried from some other reviews) and no air bubble, so I think it will last a long time.
Spending way too much time playing with this new gadget! Very recommended!
I have a good friend for a secret Santa gift exchange. He loves space and NASA related things but most space related gifts were either geared for young children or insanely expensive. Ferrofluid is the perfect in between and an interesting, fun desk object. It’s related to space due to how it was developed but won’t look silly on a adults desk.
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.
