Re: Preserving Balloons
New insight to this.
I currently took a break from doing a partial balloon room fill. It's a special occasion and so I decided to go to the "special stash". Mainly a bag of 250 14" tufftex, two bags of 14" qualatex, a bag of 17" qualatex and a half bag of 24" qualatex. And for fun I went to the ali baba stash and pulled out handfuls of wiggly worms 12" elephants, 12" bunnies.
I bought most of these two years ago.
Except for the Tufftex, the rest of the balloons are incredibly soft and incredibly fragile. I can get a good neck on the Qualatexes, but only with slow careful working it. Same with bunnie ears and the elephant trunk. But the second pressure is released, each balloon will shrink about 20%.
They have aged and become incredibly perfect for a gentle testing. Or harder testing if you have a bunch of them.
Tangent: Did you know that tour de france bicicylists ride on three to five year old tires that are generally stored in basements? Some teams by the tires a few years ahead of the race and store them. They say the rubber softens so that it grips the road better, making each peddle a fraction of a percentage more powerful.
I can tell you that two year old rubber does become more softer, if more fragile. These balloons will rip wonderfully, but never shred.
Have a great night.
