Maybe I’m just too dense to figure this out….
In: Physics
Helium is light than air. Thats what make balloon float.
WEIGHT is Mass X Graity, however, because helium is lighter than air, it counteracts some weight by providing a upward force thus making the ballon lighter despite a bigger mass.
As helium runs out of the balloon, air doesn’t enter, thus the lift force gets smaller and smaller, and the actual weight of the rubber part starts to return to normal.
