And your point certainly ties in with the allegations that they used an explosive charge rather than a chunk of caesium Point taken…I think they were simply trying to show the generic increase though, weren’t they?

The whole point of showing an equivalent mass of Cesium would be to demonstrate that a smaller bang would occur. You would have less then 1/4 of the number of atoms with Cesium than with Potassium, so you would have a quarter less Hydrogen gas released and thus a smaller bang in general. That would better highlight the actual Chemistry of the reaction which is the combustion of H2, and not the generic increase in reactivity with heavier Group 1 metals. Mitch But that’s not true.
