• ### How many helium balloons would I need to strap to my ...

So, to simulate moon gravity, we would have to exert an upward force 5/6 times this, or enough to lift up 4.5*.833 = 3.75 kg up. Helium exerts a lifting force of 1 gram per liter, so we'd need 3750 liters of helium (to contextualize this, a basic aquarium is about 37 liters, so this is the same volume as a hundred basic aquariums).
