Remember a while back when someone posted a table that showed that someone weighing that much would need that much helium and be that wide in order to decrease their weight by that much.
Because I can't find it. So can someone post another table like that or at least provide a link to it.
I would be very grateful.
helium lifts 1.25g per litre
