How to Make a Submarine Craft

Updated November 21, 2016

The idea of building a submarine may seem absurd to you, if the submarine you envision building is Red October from "Hunt for Red October" or the Hunley, a Civil War Submarine that sunk in 1864. However, if you set your sights a little smaller and think about building a submarine craft, the idea becomes a real possibility. Making your own craft submarine requires little more than a toilet roll, a marshmallow and some aluminium foil.

Tear off of a piece of aluminium foil that is large enough to cover the entire outer surface of a standard cardboard toilet paper roll. Place the piece of foil over one open end of the roll. Bring the foil over the edges of the roll and tuck it up inside the other end. This will leave you with one open end and one closed end.

Wrap a large marshmallow in a second piece of aluminium foil. Apply a small amount of hot glue to the bottom of the foil covered marshmallow and attach it to aluminium foil covered roll. Position it near the closed end of the roll, on its side. This is the hatch for the submarine.

Cut a circle out of black construction paper that is the same diameter as the end of the toilet paper roll. Apply a line of hot glue to the edge of the black circle and insert it in the open end of the submarine. Keep it as close the end as possible. Allow the glue to dry.

Cut a second circle out of yellow construction paper. Using an image of a submarine's propeller, draw the shape on the yellow circle. Cut out the shape and glue it to the centre of the black circle from the prior step to finish the submarine.


Additional details, such as rivets or the submarine's name can be added to the side using a pencil. This will give the details an engraved look on the aluminium foil. Use images of a submarine to provide inspiration for extra details.
