Don't just say you CAN… say you WILL with the Willdle!
The Willdle is a skin-safe candle that autolights and stays lit at any angle (even in high winds or under water!). While lit, the willdle produces a never-ending stream of molten wax, always at the perfect temperature!
The cup-shaped depression at the top forms a spout for precision pouring, and the colour and volume of wax can be adjusted with a dial at the bottom. Since the willdle autosnuffs when it detects it's about to burn flesh, simply pinch the wick to turn it off.
(Don't worry, the wax that's produced disappears after twenty-four hours, so you can't accidentally fill the world with it.)
