The Moon has an atmosphere so thin as to be almost negligible, with a total atmospheric mass of less than 104 kg.The effective surface pressure of this small mass is around 3 ◊ 10-15 atm.
A typical balloon filled with Helium here on earth has just over 1 atmosphere pressure of gas in it. The excess pressure is the pressure required to strech the rubber.You could inflate a balloon on the moon perfectly well, you would need just enough pressure to strech the rubber. Equally, you could inflate a baloon at the bottom of the ocean, but that would need a lot more helium."Interesting that the astronauts on the Lunar Landings didn't have pressurised gloves judging by the footage of the landings, but there you go."Is there some way you could tell or is that just a bit of "we didn't go to the moon" trolling?
