I really like marble madness and domino type games! Look at this! Who wouldn’t want this on the fridge?

You should be able to make something like this yourself pretty easy. I’m thinking PVC pipes, with magnets glued to them. There are lots of interesting types of PVC bends and fittings to make a nice mace. I love the idea of a bell at the end. I’m so making this, as soon as I have a fridge to put it on…
