Every now and then, I come across something that is simply genius. Toobalink is genius because it’s designed specifically to work with paper towel and toilet paper tubes, literally turning trash into treasure. Using the connectors, couplers and joiners, kids (and adults, too) can build and design all sorts of fun things. As a bonus, it comes with some starter tubes, so they can open this and start building right out of the box. Then it’s time to start a “Save The Tubes” campaign in the neighborhood.
