11:03Massachusetts. Basically, you you take natural rubber, you heat it up with sulfur and then whatever chemistry happens, it transforms this like sticky substance into a durable resilient material. So now it's something that you can use in manufacturing, for example, for O-rings, obviously tires, and so on and so forth. Very big deal. Enabled countless transportation and industrial applications.
