These adorable little Cupmen are a useful and whimsical tool for your microwavable lunch. Just hang one on the edge of your cup of noodles and when the soup is sufficiently hot the Cupmen will change colors. They run about $9 (in Japan) and look cute hanging on your monitor when not keeping you from burning yourself. Although I highly suspect that anyone who cooks enough noodles to want to buy one of these will already know exactly how long to put them in the microwave for and thus would have no real need for the Cupmen. But you can never be too safe I guess.
