So much emphasis is put on the weather outdoors, but indoor places become arctic tundras as soon as the weather gets warmer. How can you know the amount of layers to wear without knowing the forecast indoors? Hot Hands wants to help combat AC. 

Based on Twitter geotags, we found where the most tweets about being cold inside were coming from and dubbed it The Coldest Building in America. We put a free Hot Hands vending machine in front of it to heat up the forecast indoors. 

When users update their weather app, they will find the forecast for popular indoor places.
