Or learn to make their commentary interesting. For example, tell us about the loss of mass per second when the engines are at full chat. Tell us the rate of acceleration and how that increases as the fuel is used up. Explain why the tanks are pressurised or why the exhaust plume is pencil shaped at sea level. There's a lot of science to be explained just by the colour of the exhaust plumes. I do a few STEM talks each year and try to avoid saying anything that the room has heard before. For example, the Shuttle orbital manoeuvring engines are derived from the Apollo SM hypergolic engines that braked the spacecraft into lunar orbit and accelerated it on the way home.
Perhaps I have a retirement job opportunity but I doubt I would last long after too many "clucking hell, that's loud" comments.
