Do they have that at Circuit City Sqela, and I laffed when saw the bottom of you sig the first time. ( fond memorys of whip cream cans.)....Unfortunitly medical grade is no longer available. They put just enuff sulfur dioxide in it to make ya yack after several breaths. Believe me I got my bottle filled last week and sniffed.."just to check quality"
All though I've been told you can eliminate the sulfur through a double holed stopper and bubble thru water..................Not that I'm feeling like playing Lab Rat.
