Instructables

Step 2:

Melt candles together and attach them to balsa. Again, an electric hot knife makes this step a breeze. A heated fork can achieve the same results. Make sure to do both sides.

Once the candles are attached together, melt them to the middle of a piece of balsa wood 3/16 x 1/8 x 36 inches.

wouldn't birthday candles just melt really fast
thats the point. they burn fast. if you usedd a slower burning candel, it wouldnt generate enough heat to keep its own weight in the air
hot glue is too heavy, by melting the candles together you dont gain any weight
