Want to make a mess and learn about magnets at the same time? Here's a great DIY science experiment to try at home this weekend.
According to Science Alert: "As Dave Hax explains, all you need to achieve hours of magnetic entertainment is some Elmer's craft glue (or another type of PVA glue), a bowl, Borax (sodium borate) powder, and iron filings.
Put on some safety googles and a lab coat, and you've got yourself an afternoon of good, clean, scientific fun. Oh, and don't forget an assortment of magnets so you can play around with your magnetic slime once it's ready."
