Step 1: You Will Need:
Gadget Herdz robot
Wick- I used this twine-like string- you will have to experiment.
Step 2: Wax
The best thing you can use is candle wax.
Next, if you don't have an old candle lying around, you can use Babybel cheese wax. I used it in another Instructable that inspired this one. https://www.instructables.com/id/build_a_eco_friendly_candle/
Finally, as a last resort, you should use a crayon. They smell weird when you burn them.
Step 3: Preparing the Wax
Using a knife or scissors, stab the old candle between the aluminum holder and the wax, then peel away the metal. Watch out for sharp corners. After the holder is cleared away, there will be a little metal thing at the bottom that holds the wick. Pull this metal piece down. The wick should come down too.
Babybel Cheese Wax-
Eat the cheese. Then throw the paper thing that you use to open it in the garbage. You will need to crumble up the wax into a ball to make it fit in the melting tub.
Take the paper off the crayon. Next, crush up the crayon to make it fit in the melting tub. You will need around three crayons to make a candle.
Step 4: Just Another Wick in the Mold
Step 5: I'M MELTING! I'M MELTING!
Step 6: Finishing Up
To light the candle, simply cut off the extra wick and burn.
