I believe sulfur hexafluoride can actually be made with common household products found at your local wal-mart. There is only one way to create this gasiouse malononious. first you take water and milk, establish it into a tupperware bowl and put in microwave on high for 25-30 min or untill evaporated. Before you open the door, you must spray a layor of a mix between hairspray, dollar tree fabreez, and a previously made milk and water objective. after this, you open the door, and quickly close the top so as little of the gas emptys out. set in toilet for 3 days, so the containter is totaly submerged, perhaps by a weighted weight. leave toilet seat down!! do not open!! i cant stress this enough!! please, this is not the stage where you should be messing around! if you need the toilet, go outside, use another one! something! dont risk your family and near by neighbors... after the 5th day you realized you've forgotten about it... dont do that but if the 5th or 4th day havent came, then u should/must open it on the 3rd day. after you open it, trap in several ziplock bags and place in runnning shoes, then wait another 6 days.... finaly the gasious malononious is ready for use... fill your tub with it, and impress family and friends!! perhaps a pool, and shock neighbors and spectators... enjoy -professor Drjake Russell

I believe Professor that you are FULL OF SHIT!!
