I don't know what that photo is about, but I would quietly walk away....or run!
One of my favorite quotes is one from a book called "Ignition!", written by John Clark who was deeply involved in gubment-funded rocketry. His comment: " For dealing with this kind of situation, I have always recommended a good pair of running shoes". For folks who like rockets, are chemistry geeks (or both like me), the book is a hoot.
