I told grocery store clerk my funny story about broken refrigerator, and he, in exchange, told me something unbelievable: you can get a toy called "laser thermometer". Basically, you can point it to the wall on the other side of the street and it will give you temperature of that specific point. And... it's very affordable, I can see the cheapest model goes from $20.
Super cool toy! Wow! Now you can determine from distance if a girl is actually hot ;) I wonder how this technology works.
