  DO you mean like in the film Up? the problem is that whilst helium is lighter than air, the amount it can lift isn’t that much. Also we are actually running out of helium as when it gets released from balloons and things it just escapes into space. It’s thought we will run out in 50 years, so that will be the end of helium balloons and squeaky voices!
