Fun and ambitious desk deco which offers a nice interactive sciency vibe. I'd give 5 stars had I not purchased the LED light addition. The LED quality is lacking for what should be presented as a technical desk adornment. I'd suggest looking into a high CRI emitter in a neutral tint as to not impact the color and tone of the Ferro fluid; nichia 219b emitters are top of the line and would really make the display pop.
LED light and extra magnet for SPIKE ferrofluid display
Really love the fluid and the shipping was fast, the only problem I had was the LED light would dim and flicker a lot.
I made this purchase while I was looking for lava lamps. This is incredibly entertaining for all ages. I gave this as a gift to my boyfriend we want to purchase more for our friends.
