I made a balloon arch with a pump, after few minutes they all popped! :(
I'm pretty new at doing balloon decorations, I've done around 3 o 4 arches so far. They all looked so pretty and lasted a long time. I used to inflate them myself by mouth and leave them over night in an air conditioned place and next day outdoors and they lasted for a long time.
So I decided to buy my first electric pump for my last project, I used black and white color. 12" inflated pretty large probably 11" each. First time that I didn't tie them individually but I inflated 2 and just tied them together.
This one I made the same day and as soon I was done I put it outside. I live in Miami so weather was suuuuper hot! And after a few minutes all black balloons where gone!! :( and only few whites stayed in place...
What did I do wrong? Anything for me to change? Or should I just blame the hot weather?
