How can I make something glow in the infrared -- no flame or AC power?

For a science demonstration at my son's school, I have modified a webcam so it can detect infrared light. I would like to be able to heat up an object (I don't mind what) so that it can be seen on the infrared camera. So far, I have found that I can see a match (even after it has gone out), an IR remote control, and a gas flame. But these are all a bit tricky in the school environment. Ideally, I would have a battery powered device that would heat up a piece of metal enough that it will glow (in the IR) without anyone being able to burn themselves or set light to anything. I don't mind making the device, modifying something, or just buying something.
