With remarkable reluctance he touched the pink spot again and this time steeled his body for the icy spray. Mild water? He found suds forming on his body and he rubbed hastily here, there, everywhere, judging it to be the wash cycle and suspecting it would not last long. Then came the rinse cycle. Ah, warm — Well, perhaps not warm, but not quite as cold, and definitely feeling warm to his thoroughly chilled body. Then, even as he was considering touching the contact spot again to stop the water, and was wondering how Lizalor had come out dry when there was absolutely no towel or towel-substitute in the place — the water stopped. It was followed by a blast of air that would have certainly bowled him over if it had not come from various directions equally. It was hot; almost too hot. It took far less energy, Trevize knew, to heat air than to heat water. The hot air steamed the water off him and, in a few minutes, he was able to step out as dry as though he had never encountered water in his life.
