ton of empty cardboard boxes. we have been having a lot of fun making things out of our boxes & the cardboard.
my daughter has a great building blocks marble run set. she used to play with it all of the time. the whole family loved playing with it. unfortunately, since our move, we have been unable to find it.
i have seen a number of homemade marble runs made out of cardboard tubes, straws & even legos & i thought we could try our hands at our own while we searched for our missing one.
we used a large cardboard box. we cut the flaps off of one side to leave one
