How to Build a Cork Boat | Make a Boat that Really Floats

Written by Ryan Thompson | Fri, Jul 7, 2017

Powered by pure imagination, Handy Dan and his trusty sidekick, Junkbot, show you how to make a seaworthy sailboat out of corks, toothpicks and paper in the Amazing Junkyard of Wonderful Stuff.  Take a look!

Set sail with Handy Dan and Junkbot and learn how to make your very own boat that really floats!

Step 1: Gather your supplies

There are a few items you will need in order to make your boat:

  • 3 corks (different sizes are okay)
  • Construction paper, any color
  • 3-4 toothpicks
  • 2-3 rubber bands
  • Scissors
  • Writing utensil

Step 2: Make the sail

Use toothpicks to make the shape of a perfect square in the corner of the construction paper.

Draw a square around the toothpicks.

Use scissors to cut out the square piece of construction paper.

Join opposite corners of the square to fold the square in half so that a triangle forms.  

Unfold the triangle and cut along the crease to make triangle. That triangle is the boat's sail!

Step 3: Make the "hull" of the boat

Gather the three corks and fasten them together by wrapping a rubber band around them.

Use a second rubber band and then move each rubber band to the edge of the corks.

Step 4: Assemble the boat

Put the toothpick through the sail.


Push the toothpick into the corks.

You now have your sailboat!

Step 5: Set sail!

Put the boat in a tub of water and watch it float! 

For extra fun, and with your parents permission, use a hand fan to blow the boat around!

You may even add more sails to make a clipper ship!

Enjoy!
