Per Newsweek article

"Think of it, magnets," Trump said. "Now all I know about magnets is this, give me a glass of water, let me drop it on the magnets, that's the end of the magnets. Why didn't they use John Deere? Why didn't they bring in the John Deere people? Do you like John Deere? I like John Deere."

Incoherent rambling like usual

He was talking about electromagnets at sea ships... Because the sea-water would short them.

But then, it's almost as stupid as the short version.

At this point you can't really tell whether something is satire or a quote from the orange president.

When ever you think something sounds too stupid even for trump. No you didn't.

His stupidity is his defining characteristic among his voters. For the wealthy and powerful, he's an easily manipulable rube. For the poor saps he says the same stupid things they think and say. He's just like them, so relatable!

It sounds shocking until you remember Americans are dumb as shit. I have to keep reminding myself of this to make any sense of the absolute dystopian nightmare that somehow they support.

First Juggalo president

well... to be fair.......

Those are stir bars.

That they're magnetic is propaganda to push magnetic field bunk to sell more so-called "magnets". Stir bars are moved by phlogiston, which is why the liquid medium is often heated in tandem.
