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
- · Scrap cardboard
- · Scrap wax/candles (white is the most see-through)
- · Double boiler
- · Tape
- · Low-temp glue gun
- · Scissors
- · Xacto knife
- · Quarter (not pictured)
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
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)
Step 6: Making the Wax Bath
Cut the wax into chunks, then melt in a double boiler – grown-ups only. Warm the wax in your double boiler under low heat with constant supervision. If it is too low to melt the wax, slowly raise the temperature. I ended up going to medium high (but my stove top may be different, it seems to be possessed anyway). I used a plastic spoon to stir it as it melted.
When the wax is ready, take it off the heat and place it on a drip-friendly surface (I used a trivet placed on my kitchen floor). If your short companion is helping, be very careful about burns!!! They might be able to dip some of the boat, but an adult should do the rest as it starts to get coated in hot wax.

Step 8: Finished!
Do whatever floats your boat!!!
