I saw someone giving tips on hair bounce on twitter and was like "I have never animated something like this yet" and tried it out :P Hair is too bouncy for the movement in my opinion.
Lets assume that the person is stuck in a point in space about 100km from the atmosphere of Jupiter and won't move from its place so that all energy will be used on the sneeze instead of being wasted by being blow in the opposite direction. The human and his lungs are also indestructible.
Based on the average speed of a human sneeze, how many times faster does it have to go to launch the sneeze so fast that it blows off half of Jupiter's atmosphere?
