Helium is abundant in the rest of the Universe, but relatively scarce here on Earth. The reason? Helium can escape Earth’s gravity and dissipate into outer space.
Unfortunately, most of that helium is found inside stars like our sun. You can go get as much as you want, but to keep from burning up I’d advise you to go at night.
