Amazing Ferrofluid Magnetic Display in a Bottle, Ferrofluid Magnetic Liquid Display Desk Toy, Magnetism Science Kits by C&H Solutions

Really fun for my son who loves marvel and Venom. It’s fun for him to use his imagination and pretend it’s really an alien. A little smaller than I expected but he was happy with it.

Neat little thing. Very strong magnets. Overall great desk toy.

Neat novelty item. My grandsons think it's pretty cool to play with.

This is so incredibly cool!! I bought it for my son, however I use it sometimes as well. It is so awesome how it moves!

There is a good amount of ferrofluid in the flask. It is super fun to play with. The magnets are VERY STRONG. I would not let a child under 10 near the additional two magnets (death hazard if more than one is swallowed) and younger children should be surprised when playing with the other two magnets due to pinching hazard.

This is fun to experiment with, but after only a few minutes, the magnets were chipped.

Product arrived with broken glass in package. Fluid had also leaked. Shipping box with other items were all okay. Please see photo attached. . I want this excellent product as a demonstration of ferrofluid for my grandchildren. Amazon return / replacement process worked perfectly.

This product is amazing! It is the perfect size and is easy to carry around with you. I cannot overemphasize how cool this thing is. It comes with two magnets (Four, if you count that each magnet can separate into two). The magnets are very, very powerful. I haven't had this happen to me, but don't leave the magnets on the ferrofluid when you store it because it will permanently ruin it. It is fun to bridge the ferrofluid back and forth with the magnets, and I could sit there and mess with this thing for a long time. If you are having doubts about getting this, so did I until I got it and saw how much better it was than I thought. This is an awesome product!
