Did you know that it is possible to turn a pile of flattened cardboard boxed into a water-worthy cardboard kayak? Well, it is and it can all be done for less than $40.
All you need to make your very own waterproof, cardboard kayak is 1 gallon of waterproof wood glue, a paint roller and tray liner and several flattened cardboard boxes (and patience).
Just be sure to laminate the seams so it doesn't sink!
