Crayons

Lay three crayons side by side, and measure string to fit the three crayons.
String

Cut string to desired length (preferably small).
Tape

Break off a piece of tape, lay sticky side up, and put two crayons on it so they both stick.
String

Place the length of the string on the two taped crayons so that it is inside of the middle of the crayons.
Third Crayon

Carefully place the third crayon on top of the two others and the strings so that it rests on the other two.
Tape

Slowly wrap the tape around all three crayons and be careful not to move them.
Wire

Select a desired length of wire (6 inches)
Wrap

Slowly wrap the wire tightly around the three crayons so that they are held together at the top.
Wrap

Now do the same thing down by the tape.
Remove Tape

Slowly remove the tape and adjust the wires so that the top is near the half mark and the top of the crayons, and move the bottom wire so that it is close to the bottom of the crayons.
Trim String

Trim the string so it is close to the tips of the crayons.
Light

Light the string and make sure that it stays lit for a few seconds, in a survival situation, this can burn for around 1 hour.
After

You can light these in the dark and produce quite a bit of heat.
Extra
