Uncertainty of Warmth I cast naphthalene butterflies in daily basis for three months, as if keeping a diary. By keeping a diary, I mean that I cast them as my mood dictated, not that I cast exactly the same amount of naphthalene every day. Some days, I did not cast at all, whereas I sometimes cast two butterflies a day. Therefore, the cast naphthalene vaporized in various ways and speeds. I put a date tag on a butterfly, and put it in a case. The flowing time stopped for a moment.
