An intuitive and delightful stick-anywhere heat indicator
Inspired by pores in plant leaves
Pores in plant leaves (called stomata) undergo an efficient mechanical and chemical process to open and close in response to sunlight. I was inspired by this process to create a domestic product that opens and closes in response to cyclical changes in temperature.
Thermometers can tell you the exact temperature, but are often difficult to read and dull to look at. I saw an opportunity to create a form that delightfully indicates temperature change at the glance of an eye. I tested many possible forms using bimetallic strips, which naturally flex because of different rates of heat expansion between the two metals.
