A while ago I told you about our treasure box, where we keep all sorts of odds and ends that are just too full of potential to throw away. Well, apparently I have been having some hoarding tendencies because that treasure box had gotten pretty out of control lately, overflowing with treasures. Something had to be done. So we started using the materials in our treasure box to build different inventions, and it has quickly turned into our favorite rainy day activity! I’m sharing all of the details of how we do it over on Modern Parents Messy Kids today.
