The picture shown in the Cryophorus article is wrong! The ice isn't forming in the evacuated bulb (on the right side) but on the surface of the liquid water in the left bulb. The ETH Zürich has some photos of such an experiment which shows the real effect.

- You are completely right! The whole point is "freezing at a distance", in the left-side ball, caused by immersing the right-side ball in snow. This is quite clear from (e.g.) Wollaston's original article. I have now replaced the misleading picture by Wollaston's original drawing (which is of course PD because Wollaston died in 1828). --Jmk (talk) 09:15, 24 November 2022 (UTC)
