Tony nodded. Of course it was an invention. If there was a potion that existed that did this he would have had a much harder time keeping Bruce away from it. He watched as the kettle turns away before looking at Meru curiously. "What else are you working on?" Because he was nothing if not direct, and if the notes on this potion weren't something he could view, he wanted to see what else was going on in the lab.
He picked up one of the cups of tea and sipped it, moving around the room to look at the varied potions bubbling away. He was pretty sure this young man would be getting one of his internships if he applied for it, so he wanted to see what else he was good at.
