Trump boasts of hydrosonic toothbrush missiles again

"Hypersonic missiles – we have hypersonic and hydrosonic. You know what hydrosonic is? Water!"
— Donald J. Trump, December 5, 2020

At a rally in Georgia tonight, Donald J. Trump boasted of America's military strength, and specifically of our hydrosonic missiles.

There are no such missiles.

There is a "Hydrosonic" brand toothbrush.

It's a decent electric toothbrush.

It is not a missile.
