Nobody likes a melty chocolate bar, nor does anybody like a cold, rock-hard chocolate bar. But how is one to know if your sweet treat is at the proper temperature? Oh, if only there was some way technology could come to our rescue on this pressing issue!

Well, my friends, now there is. At least there is if you're dealing with the DARS chocolate bar of Japan. It's got a little spot on it that changes color with the temperature, letting you know if your candy bar is too hot, too cold, or juuuuuust right. Yep, we're just taking very, very small steps towards a perfect life. Patience, people. — Adam Frucci
