Very odd, the quote post function worked perfectly here but not in another recent one. +1 for casting your magic MacSpell over it.

MigL Posted September 30, 2017 Share Posted September 30, 2017 If your nephew was still alive, he'd slap you upside the head. If the chair isn't pushing up on your ass, what's keeping it from hitting the floor ? You're in a negative gravitational potential that's accelerating your ass towards the floor at 10 m/s/s. Have someone kick the chair from under you and see what happens. Link to comment Share on other sites More sharing options...
