That's a very delicate situation. You can definitely try, but its about time, place, and reading their reaction. Do you have any presentation material? Improvising is very hard to do. Its extremely difficult to convey a complex concept, and there's absolute no way they're going to understand it as well as you do. For this reason, there's no way they'll understand the value of your concept as much as you do. Find the right venue. If you have an opportunity to give a formal presentation, then prepare for it. If not, you'll have to improvise. You can't demand other's attention, so you'll have to find the right time.
