Helium is a lighter gas than the nitrogen/oxygen that our atmosphere is composed of, so a helium balloon will naturally float up. It pops because the gas inside the balloon expands as the balloon rises to higher altitudes where the air pressure is lower.

It soars upward because helium is lighter than air, but then it pops when the pressure inside the balloon becomes greater than the pressure around it. This is because air pressure decreases as elevation increases.

Air pressure on the outside of the balloon decreases and there for expands until it pops.
