Temperature-Sensitive Baby Bottles Edit
Thermochromic Ink is Green When Milk is Warm, Red When It's Hot

Every parent has his or her own way to determine if the milk in their baby’s bottle is at the right temperature for consumption, but this Baby’s Bottle by Huang Tzu-Yu, Cheng Hung, Wang Tzu-Wei, and Xiang Yu-Wei eliminates all of the guesswork.

The Baby’s Bottle has a face printed with thermochromic anti-forgery ink. When milk is at 38 degrees Celsius, the face is green and smiling. When milk is at 45 degrees Celsius, the face is red and crying. The color cues make it easy to assess temperature from afar. The designers won a Red Dot award in 2008 for the Baby’s Bottle.
