Hello to everyone.
My first question on this forum (it was quite tricky thinking of a heading and prefix for this thread!):
Imagine for a moment that there is a hot air balloon which has a strong shell forming the balloons shape rather than one made from material and it weighs the same as a normal hot air balloon, What would happen if air was gradually drained from the balloon, would it rise?
