Dancing Ferrofluid with Music Rhythm, Ferrofluid Speaker Music Mate, Symbiote in a Bottle, Ferrofluid Display Lamp, Desktop Decor, Teenager Gifts (Not A Speaker) (Does Not Make Sound)

The media could not be loaded. This thing is soooo cool! Def reccomend. I am obsessed with watching it. Piano music is soothing, house is wild to watch! This thing is so so cool!! I wish I could afford one in every room!

This is the most mesmerizing desk accessory I’ve ever owned. The ferrofluid moves smoothly with the magnet and looks futuristic. Great gift idea or conversation starter! Wish it was an actual speaker though.

My son wanted a ferrofluid bottle for Christmas and I didn't think it was that big a deal. He let me know right before Christmas that was one of the things he really wanted.So I ordered a cheap $30 ferrofluid bottle. But then I saw this and thought, "Maybe this will be cool too."Boy was I right!! He LOVES this gift and while it wasn't super cheap, it was by far and away his most appreciated gift and I felt really good about it because it showed I was listening and I went above and beyond what he had asked for.That said, how well does it work. It is pretty solid. You aren't going to get wild, bottle filling gyrations, but it does dance with music or talk. It responds very well to lower frequencies. And it is very neat that it has a battery, so when you unplug it and haul it around, you don't have to plug it in again to get it to work.This is a really clever design, would be great for a science teacher, and for any science minded person who "has everything."

This is a nice desktop device that does work fairly well. However the fluid does start to separate after a bit. Still okay for the price and novelty.

A band had one of these setup on a guitar amp dancing around during a gig. and I loved it. Needed to buy one. It's kinda silly with no real reason anyone should own it, other than it's SO COOL! I love having it on.

The media could not be loaded. Worked well for a week or so, but now there is a brown air bubble that has separated and it completely ruins the aesthetic. I only used the device a handful of times before this happened.Seems to be an issue for others, so I would buy with caution. For $129, I expect better.Amazon is saying I cannot return it, so I am hoping this review finds its way to the company. Would happily update the review if they can help.

This is really fun product to set up on the side of her room whenever dancing and romping around. It picks up sound very well and dances quite like it says. I am a little disappointed that it's not a speaker in of itself. I think if they added a speaker to it, it would really bring the whole thing together.

The media could not be loaded. This was a speculative purchase for me. Kind of expensive, not sure if it would look good or really work.Turns out the whole family loves it. The video shows how it works — music is playing in the room (not from the device) and the ferrofluid dances around. Backlighting makes it work and stand out. It looks like an AI animation but it’s a physical, real-world effect. I was also worried that it would look/feel like a cheap thing but it’s nicely solid and dense and feels like it’s quality-made in your hand. Charging is easy with a USB C port.One caveat — don’t leave the magnet permanently attached to the glass … it will magnetize the ferrofluid, or at least that’s what I think happened to me.Great purchase, would buy again and will probably gift come winter.
