The video shows several incorrect attempts to melt the ice before revealing the correct solution. Do not use a flamethrower, speaker, hot coffee, puppy's tail, goldfish, hot soup, hairdryer, or the sun, as these methods are ineffective or incorrect for this puzzle.
The puzzle's solution is counter-intuitive, requiring a 'spicy' approach rather than conventional heat sources. Look for items that can generate intense heat in an unconventional way.
