This week Reactions is taking a look at the chemistry in your beer foam. Science can help you get rid of that head fast. Find something oily like a french fry or a slice of pizza. Even your oily nose will work in a pinch. Get a dab of grease on your finger and swirl it through the foam and watch those bubbles disappear. Why? Well, you’ll just have to watch the video, won’t you!
