My niece is an aficionado of slime. Some gunk from mixing contact lens solution with baking soda and glue. She has dozens of different recipes. But she’d never heard of magnetic slime. I used to have some grey silly putty that would slowly eat a magnet, and got the idea to give her this.Mix a couple of tablespoons of this in *while it’s still liquid* and the resultant slime is attracted to magnets. Since slime is a much lower viscosity than silly putty you can see the reaction in real time, which was cool.Wear gloves and cover your work surface.Once it’s thoroughly mixed in and the slime is cured or whatever, it’s still messy but not too bad.If you put the powder in after it’s no longer liquid, it will stick to the outside, and to everything else, not work as well, and make a huge mess in the process. Don’t.The slime will be pitch black, look like tar, and possibly make the child’s mother ask if she’s become Venom.

It's really bright blue. Perfect color!

I am using this to color lime plaster, I like the result I am getting.

Horrible product does not function as advertised. Also leaked all over the house due to poor packaging. Vendor refuses to help siting regulations won't allow a refund.

Product arrived damaged. I’d have to take it to the store to get it replaced but no time to do that. My husband will attempt to use it and hope it works.

Excellent Value, comes in a plastic jar with screw on lid, which I prefer to the bags.

Product was as expected and arrived very quickly
