An alert viewer points out (at 5:12) that in fact you could fit 18 Mercury's into the Earth not 153. Sorry for the blunder. He added that “Ruspolia nitidula is a cricket, not a grasshopper it is not native to the Americas” which is also true though it is often called the “cone-headed grasshopper” so that mistake is less embarrassing especially as the news story did call it a grasshopper.
