Bulk Iron Filings- 1 LB Iron Filings for Science Experiments, by American Heritage Industries

My daughter and her partner chose Slime as their science fair project. They made several slimes- glow, foam, butter, snow, some others and magnetic! The magnetic slime was my favorite. It was fun watching the girls make all their slime like mad scientists; the measuring, pouring, stirring, scrutinizing and laughing. They had so much fun. We bought these iron filings for the magnetic slime. We still have lots left over and these girls made SLIME. Not sure what to do with the leftovers… more slime? But I really liked using a magnet to pull the slime up a glass container, watching it stretch and move was neat. I was surprised how little of the iron filings were needed. It seems a little but goes a long way. It did not take much to really darken the slime and do its magic. I highly recommend letting children make slime. Let them be scientists and messy and explore and do it with friends. Get a strong magnet and use these iron filings to create a quality magnetic slime. It was super cool! Not sure what else one does with iron filings but I am looking forward to the kids next adventures in slime.

It worked surprisingly well as a tool to strip copper out of a solution. I was able to eventually cement out copper on the powder with remarkable speed but had to keep the solution moving with a magnetic stirrer, lest the cementing copper turn the iron powder into a glob. It was difficult to work with only because I had wanted something I could pour my solution onto and forget while the copper cemented out. But that just means either I'm lazy, or it wasn't ideal for the task I wanted. I can't complain about the price or the quality. If you need powdered iron - this'll definitely do.

I bought this for the kids to make magnetic slime. It definitely works, and a good value

It is what I wanted to help grandkids understand magnetic fields

I bought this for my son to try different experiments. It’s cool to use different magnets to see how it reacts!

I weighed the product, including the plastic bag, and it weighed .97 lb. Not a big deal, but if you were going to be a bit more generous, say, 1.01 lb. would that really impinge on your profits?

Used this for magnetic slime. Worked great.

I’m making some resin art pieces and want to make them magnetic so fingers crossed!

Perfect for physics!

It was perfect for a rusting effect on some props. I created the rust effect with salt, vinegar, and hydrogen peroxide after adhering the filings to the workpiece. Warning; When I used a topcoat (protectant) lacquer it darkened the effect, so do some experimenting with a very light sealing topcoat.

Finally got around to using this. We made make magnetic slime with Emily's science lab magnetic slime experiment and it worked out great. Kids loved it.
