I think I broke it at my last try

I handed all the things, the second last was the magnet, and since time almost was up, I shoved the knife at his hand rightly after, before he even asked for it. But he kept asking me for the magnet (which he already had, it wasn't there anymore) and called me stupid for not telling a magnet from a knife

And the timer froze, and nothing exploded, he just stubbornly wanted the magnet.
So I left him to his own tasks *shrugs*
