I love TED videos and I just saw this one, which is made for my blog: I am a former scientist and I love baking cookies! If you ever wondered what’s happening when you bake cookies, have a look at this.
You stick cookie dough into an oven, and magically, you get a plate of warm, gooey cookies. Except it’s not magic; it’s science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we can kill salmonella, and why that intoxicating smell wafting from your oven indicates that the cookies are ready for eating.
