I think we can say that after seeing so many mutagen canisters (and even Mutagen Man's "jar" thing) bouncing around NYC without shattering. What? I was talking about when Donnie was testing the mutagen earlier in the episode and the mutagen itself had shattered when it froze, not the canister. Then, when Mutagen Man ingested the bad batch he didn't shatter. He just froze.
