Hi all, The answer to a Jeopardy question tonight was "oasis", that green foam used in flower arranging. I knew the answer, but then my roommate asked what it was made of. That I didnâ€™t know. Iâ€™ve just been trying to find out on the internet, but the information certainly isnâ€™t easy to find. Does anyone happen to know what this stuff is made of? M.
