What I loved about the swimming through bubbles myth was not that the myth was plausible, but for different reasons than they expected, but that the different reasons were so much simpler than the original hypothesis. Adam and Jamie thought that maybe you couldn’t swim through bubbles because they changed the water density- no, its because they cause the water to move. Simple.
As for splitting the tree, they may have put the smallest amount of explosive that would detonate in each bag, but 25lbs of explosive, really? Try 10lbs before you tell me you used as little as possible.
