Okay, so I bought this Black Iron Oxide Powder mainly to spice up my niece's slime game. Let me tell you, it did NOT disappoint! Mixed a couple tablespoons into her gooey concoction while it was still liquid, and boom—magnetic slime! Watching it react in real-time was oddly satisfying (and yes, her mom DID ask if she'd turned into Venom).

Pro tip: WEAR GLOVES. This stuff gets everywhere if you're not careful. Also, mix it in while the slime is still wet—otherwise, you'll just have a messy disaster (trust me on this).

Beyond slime, this powder is crazy versatile. Used it for lime plaster and got a sleek black finish. Comes in a sturdy plastic jar too—no annoying bags that spill everywhere.

Only downside? If you're firing ceramics, expect a brownish result instead of pure black. And yeah, my first order arrived damaged (ugh), but the product itself is solid.

Final verdict: 10/10 for creativity fuel. Just... maybe keep it away from white carpets.
