TMBG are cool because they explain seemingly complex scientific things through song.
One of my favorite TMBG songs describes fusion on the Sun:
“The Sun is a mass of incandescent gas, a gigantic nuclear furnace
where hydrogen is built into helium at a temperature of millions of degrees
The Sun is hot, the Sun is not a place where we could live,
But here on Earth there’d be no life without the life it gives.”
