If the detonator then exploded the main charge (see mercury fulminate), then it could indeed trigger a major explosion. As Dr Vincent says: "some mad boffin could spend some weeks of his life devising such a device". Walter is certainly a little mad and terribly clever, but he fashions the whole thing in a matter of hours.
