Shaped explosive charges...with lots of demos. There is a lot of physics involved and your audience will stay wide awake. You can start at one end of the explosive energy spectrum with fireworks, and end at the other end with the shaped charge that squeezes the nuclear package of a fusion bomb to cause the package to go critical. And there are a lot of shaped charge applications in between you can address.
Another thought is string/M theory. It's premises and conclusions are so way out, they are bound to raise a lot of discussion. For one, is this really a theory...or just a WAG? [See sources.]

I would make sure that whatever you talk about involves a pretty picture. Audiences like pretty pictures.
Liquid crystals are often very pretty.

So are the images from atomic force microscopes.
