Iron Filings (Palo Alto, near Cal Ave)

I have half a gallon of iron filings that I bought for fun. Iron filings is the black, coarse "powder" that is used at children's museums for exhibits with big magnets. Iron filings and magnets make for a lot of fun. The filings can stain clothing and carpet so if you want to set up a play/tactile experience using them, you will want to do so outside or in an area without carpeting.

I would keep them, but I am moving and can't take anything that isn't absolutely necessary/
