How did the first wife build the bomb with with the pliers? After all, he took the pliers from the first wife over to the second wife's house, and he said he forgot to bring them back. Unless of course, she made the bomb before that, but they gave the impression that she decided to make the bomb after having built the first volcano (she said building a bomb wasn't harder than building a volcano.). He got the idea to make the volcano for his second family after watching her build it. So I was confused about the timeline since he took the pliers over to his other family.
