Just to assauge the helium debate, taken from a scientific journal:
Helium is commercially extracted from natural gas.
When you cool natural gas to below -164 degrees Celsius, it liquifies,
and what is left is mostly helium.
It seems unlikely that you could do this at home, as even North Dakota
rarely gets that cold.
If you just want something to lift a ballooon, natural gas (mostly methane) itself
will work, and hydrogen is easy to make.
There's many ways to make helium :)
