Balloons do not, in fact, go up anywhere. They just repel the ground which itself moves away from the balloon as it serenely floats in the same position. It's not common knowledge but I suspect this is due to the elephants, propping up the ground, bending their knees in anticipation of the balloon bursting.
You can amplify this effect if you add a wicker basket containing mice to the balloon.
