How far in advance can I start my balloon tower?
How far in advance can I blow up the balloons?
I want to do 2 balloon towers for my son's birthday that are about 5' tall. The party starts at 5 pm and ends at 9 pm. How early can I blow up the balloons and build the tower?
I suppose you are talking about air filled balloon columns (or towers, as you called them).
Some professionals blow up their air filled balloons up to 3 weeks before the event, but I would suggest you should inflate them a maximum of 5 days in advance.
Store the inflated balloons in a large, clean plastic bag that closes tightly over the balloons. Otherwise the balloons will oxidize and lose their shiny surface.
Large trash bags (55 galloon clear drum bin liners) will do the job just fine.
Good luck with your son's birthday.
