Optional: small flat weight (coin or clay) for ballast
Steps
Cut a little hole in the milk carton the size of the straw.
Insert a straw through the top as the mast, securing with tape.
Cut a triangle or rectangle from paper and thread the straw through top and bottom to form the sail.
Place the boat in water.
Adjust the balance by repositioning the mast or adding a small flat weight (such as a coin or small piece of clay) to the base if the boat tips to one side.
