Very interesting. I was curious so I googled, and came across this:
"Bounce Ironing Spray contains patented polymers. The polymers also pull humidity from the air while you wear your clothing, relaxing the fabric and preventing wrinkles from returning. It is safe on all fabrics."
I asked my husband (the walking encyclopedia) what a polymer is, and he replied that it's a plastic, like Flubber.
I'll have to do some digging, see if I can get a free sample too!
