With Australia in an overwhelmingly dominant position to reclaim the Ashes today there have been rumours that the English side is literally trying to make it rain.
Cloud seeding involves dispersing chemicals, usually silver iodide, into the atmosphere to induce precipitation, i.e. rain.
Academic research has shown that cloud seeding statistically does not work. But England's chances are so low that some see it as worth a shot.
If the rains come in Perth today and wash out the match then England still has a chance to tie the series and hold on to the Urn.
