This weekend I spent some time with my boys teaching them a little more Kitchen Chemistry. I’ve been doing a whole series of kitchen chemistry experiments but this one was definitely a lot of fun. I got to teach them a little more about magnetism (as I did in this movie: Magnetism in the Human Body: Lessons for Ten Year Olds).
This time I was teaching them all about rare-earth magnets and how they could be used in a solution of Borax and Bemews catalyst to form an extended hydration network and grow blue water balls. Admittedly these hydration spheres centered around the magnetic ions don’t persists for very long but nevertheless the experiment is a fun one for kids!
