I have done it, and in my experience mixing is a problem. You need to mix it more vigorously than the person did in this video. Even if this is a problem, steam sparge test can also be done with 2 kg > cool water that is easier to stir. I do not think that would be enough volume of water to condense all the steam. The steam escape from the water. > Even better if they have freezer available, then sparging test can be done > with 1-2 kg -18°C ice. That would involve a phase change, which complicates matters. - Jed
