A chemist attempted to make methyl magnesium bromide by adding strips of magnesium metal to a solution of methyl bromide in diethyl ether. Despite gentle heating, no reaction was observed (i.e., the magnesium metal was not disappearing) so the chemist added more magnesium strips that were freshly cut into small pieces. This time the reaction proceeded quickly and all the magnesium was consumed. Explain.
