We always love good, cheap entertainment. This wind up toy race track is just that. The boys find silly wind up toys in their stockings sometimes or you could pick some up just for some fun entertainment for the kids.
If you have more than 5 people just print out more and lay them next to each other. Or spread them out if you have less.
They don’t go in a straight line and sometimes you have to re-start them, but it’s just a fun, simple game that doesn’t need much explaining. You can use whatever toy you’d like!
