Float or Don't? Build a cardboard boat!

It all began with a real cardboard boat race…

Then the threat of “Battle Boats” prompted a unique design concept… CARDBOARD TUBE TRUSSES! And the unsinkable surfboat was born! 

This makes a fantastic team or family project! Adult supervision / help needed for cutting the cardboard. 

Printables included so you can award medals and participation badges! Just add ribbon!

This is definitely a fun family project! Build a cardboard boat!
You can even take your dog for a ride on a cardboard surfboat!

Basic material suggestions – exact amount will depend on size of project planned:

  • Cardboard
  • Duct tape – 2 rolls per team
  • Plastic tablecloths – 3 per team
  • Cord (to tow your boat if desired)
  • Empty gallon jugs of water (to use as scoops to paddle your boat)
  • PVC poles (to be used to build paddles)

Planning materials:

  • paper, pencils, pens, sizing table, tape measure
  • calculator or smart phone

Cutting materials:

  • sturdy scissors
  • utility knife or box-cutter (adult supervision / assistance required)
  • straight edges (quilters rules work great)
  • cutting mat or other table protection… cardboard works for this, too

And of course, you’ll need a pool or other body of water to run your races / tests. Just not an alligator-infested lagoon! BONUS: printable medals included! Just add ribbon.
