How much weight will a 12" balloon hold?
I am renting an octagonal shaped hall that has a balcony all around it and a high cathedral ceiling. I would like to have swags of tulle hung from the balcony across the center of the room. There are no supports or columns at all in the center.
If I were to use 12" latex helium balloons to hold/lift the tulle up in the center, how many will I need? The span is approx. 15-20'.
So the tulle swags would be pretty long. Is there any way to calculate approx. how much weight each balloon would hold?
