How cool is that?!?!?! Congrats to your son and his friend, and to you! What great engineers! I never even heard of such a thing, cardboard and duct tape boats! How cool! Which boy is your son? The one in the front or back of the boat?
I was always just happy with a big box that made a fort or a imaginary car or spaceship or something!!! If only I knew the potential!
