This post is the result of having a small amount of downtime and having some science fun. I generally look around to see what I have to try in an experiment that may be interesting. I wanted to see what falling iron filings might do with a strong neodymium magnet and thought that an hour glass might be interesting. Although I did not have an hour glass, I did have two Erlenmeyer flasks that simulate an hour glass. So, 15 minutes later I had something that looked like an hour glass. I had to make a metal restrictor to reduce the flow speed of the filings with a small hole, and it worked fairly well. With a small amount of epoxy, the hour glass was ready. Since iron filings are ferromagnetic, each one becomes a tiny bar magnet. As the filings get further from the magnet, they collapse and fall toward the magnet. It seems possible that magnetic Gauss could be measured by the height of the stalagmites. The experiment is very simple and really is an “Odd n’ End”.
