Abstract: A color-changeable toy having a toy body to which a quasi-reversible thermochromic material is applied in a pattern. This material stably holds either of two colored states in a range of ordinary room temperatures. However, the material reversibly changes to one of the states above this range and to the other below this range. Thereby, by using commonly available heat and chilling sources such as ice, hot water or breath, one of the colors can be selected. A breath blow pipe can be used in conjunction with the toy and have an external appearance associated with that of the toy, e.g., gun and soldier.
