10. DIY Sandbox
Look, not all of us can afford a summer vacation on a sandy beach. But all of us that have yards can afford to give our kids the pleasure of playing in the sand. It doesn’t cost much, and you can even include your kids in the DIY project, and ask them to help you building the box. This way, they will have fun while building, and after. And the best part is, since they are included in the building process, your kids will appreciate the box even more.
