Helium Filled Balloon Arches
Outdoor String-of-Peals Arch with Large Balloons (found on Pinterest)
I have a customer who always asks us to build a helium filled balloon arch for her. This customer needs the arch to last 30 hours. Last time we built her the arch, even treated with ultra hi float, the arch fell within 20 hours.
I believe humidity played a factor in why it didn't last. This was for a trade show last July in Chicago so a hot humid day and the loading dock doors constantly open.
I have tried to sell them an air filled arch but they won't do it. I was thinking of going up to 16 inch balloons for them this March, but not sure if I should walk away from the job so my business isn't hurt by the bad reviews, or if a 16 inch balloon will hold up for the 30 hours they need. I would of course treat the balloons with Ultra Hi-Float again.
