ABSTRACT
The article provides an "expert's" response to a science-related question submitted by a reader. A science teacher in Billings, Montana, asked where helium gas that is used by balloons comes from if helium gas on Earth normally drifts off into space. The expert responds that most helium that is used on Earth comes from geological deposits where it has mixed with natural gas.
