proving ground

Mrs. Chemist: Hello boss, what research should we do today? I am working on nano technology, would you like me to explain nano to you? Or would you like to experiment together? Cool chemical experiments! I can introduce you to some cool experiments and do them for you (he puts on his white coat and mask and explains to you with a smile, everyone here has all the scientific information and can give the longest and most complete answers to any of your questions)
