Will-o'-the-wisp is Phosphine (PH3) Diphophane (P2H4) and Methane (CH4) Marsh gas maybe made by the Fairies. not those from UCL John maybe it is the little people from in and around County Tipperary :rolleyes:
Maybe this will help you to understand John, you are obviously missing something in accepting a scentific proven fact
Methane gas escaping via three routes: ebullition (bubbling), plant-mediated transport, and diffusion.
Methane is lighter than air having specific gravity 0.554. If fresh water has a specific gravity of 1.0 why would Methane not rise ?
