Hi,
I've read and 'tested' different sorts of strofoam both used in packing of goods ...
*
"hard type" usually found either in balls of different sizes or compacted together and the 'Bad' Type..fwhich is flexible & spongy looking ...but which when compressed stays compact & in contact with water becomes "gooey"
* sorry wont let me upload 2 photos i just took of the 2 'types' i'm refering too..hope the written explanation is clear
