This was a great find. The bottle is the size of my spice collection, and the top actually comes with a pour/shake top just like the spices do! We had a great time putting the filings in zippered sandwich bags, then laying them over a magnet. You can see the shape of the magnet's magnetic field if you shake them gently (with the top layer of plastic lifted slightly for the 3-D effect). Strip magnets from the fridge create a different pattern than standard N/S pole magnets. I also noticed that a little goes a long way with these. This should last quite a while.

The iron fillings are a great tool for my instruction on magnetism and magnetic fields. The students were amazed to see how the fillings moved around creating the field lines.

Fun stuff to play with magnets. The only minus is the cap top doesn't work as designed. It comes with a spin top that allows you to pour out at different rates. However, the fillings get stuck in the cap so that it doesn't spin. And then the fillings that are stuck can 'leak' or fall out of the cap. Not sure why they just didn't use a simple plain cap in the first place. We just keep it in a zip lock bag.

I am going to resist my urge to provide a sarcastic product review. I will say this is a bottle of iron filings, if that is what you need this is it. Be aware that it is very very fine, (think grains of salt or smaller). If you get this for some purpose other than using with magnets i would recommend you get a strong magnet to assist in cleaning up the inevitable spills. I used this for wiring my finished upper floor from the basement.... yea i know "what does iron have to do with home wiring?"... well i was originally going to place a series of strong magnets on the floor upstairs then see where along the basement ceiling the filings were drawn to and use that as the marker for my drilling points... unfortunately even the neodymium magnets (the 1" cubes) was not enough for this. What did work however was pouring some on the upstairs floor and sliding the magnet along from downstairs with a person upstairs telling me when to stop sliding. Not perfect but it works when you don't have great landmarks to measure from or a very narrow margin for error.
