Would it be possible to make tea in one of the small demo tubes? as this really make it easier to take when camping or on picnics

Yes, it would work just as well. There is less area exposed to the sun, but correspondingly less volume, so it should heat up just as fast.

The main problem is that they are less easy to get hold of, as they are produced only for demo units - therefore manufactured less frequently and in fewer numbers
