The device works by spreading the heat – produced via nanotechnology using molecular-sized tubes of carbon – with the unique iron-like ceramic unit until the bread is toasted to a suitable brown, crispy taste you want. On the top side of the toaster, Heat-sensitive illustrations of vines and butterflies appear and multiply as the bread becomes more brown. These serve as indicators of how brown your bread will be. It takes two to three minutes to toast the bread, that makes it slower than the original toasters as only one side can be toasted at a time. The reinforced ceramic toaster contains highly-durable CarbonNano tubes that will not over-heat and will protect users from any skin burns.
