Picture of Cardboard Boats

Cardboard boats!  Fun for big and little ones alike.  Plus, if one of your nautical vessels should crash, sink, or float away to broader horizons, it isn’t a great loss (more of an opportunity to make some new ones).

Step 1: Supplies/Tools

Picture of Supplies/Tools

  • ·         Scrap cardboard
  • ·         Scrap wax/candles (white is the most see-through)
  • ·         Double boiler
  • ·         Tape
  • ·         Low-temp glue gun
  • ·         Scissors
  • ·         Xacto knife
  • ·         Quarter (not pictured)
Tape and hot glue are interchangeable in this instructable, so I made both kinds of boats.

Step 2: Planning the design

First, it was worth the extra effort of making a paper version to flesh out what I had in mind.  I taped the pieces together to get the general shape, then took it apart and edited my design.

Step 3: Cutting!

Using the paper boat as a template, I cut the parts out from the scrap cardboard.  You can use either the scissors or knife, but the knife is definitely not kid friendly.

Step 4: Prep the pieces - bending

Pre-bend the boat into shape before assembling!

Step 5: Assembly

Starting at the stern (the back of the boat) start to attach the pieces using tape or glue.  It helps having more than one set of hands at this stage, so make sure you enlist your mini-sailors at this point.

If you are using tape, you have to slit the tape into several “tags” so that it wraps around curved surfaces.  [What a great teaching opportunity to discuss geometry]

Don’t forget the rudder!  I did and had to cut through the back of the keel to insert it.  Using a quarter, insert it between the two hull pieces; secure with tape or glue.  The rudder is heavy enough to keep the boat sitting in the water properly (otherwise, it immediately tips to the side – teaching opportunity to discuss water displacement)

At what temperature do you double-boil the wax roughly?

Thanks for bringing that up!

Under constant supervision, put your double boiler on low heat. You can always raise the temperature slowly, if need be.

@MrCantThinkOfAName: you really don't need to keep it melted for long. When I was dipping the boats, I had it sitting on a trivet completely off the heat (you can actually see it in step 7 - the trivet is sitting on my ruddy kitchen tiles).

Thanks for the comments! I think I will edit the appropriate steps. :)
I'd probably guess medium to high temp to melt it, and then a low-medium to keep it melted.
