Description:
UNSAFE, NOT FOR KIDS! Main article: http://bit.ly/TNXQ7 http://amasci.com/amateur/liquid_n2.htmlCan't get liquid nitrogen? Then make your own -80C/110F version by using Dry Ice. Note that this science demonstration involves several major safety hazards, and should only be performed by skilled educators. If used for science fair projects, close parent/teacher supervision is required.But also go see http://bit.ly/EKqgi SFGATE: "The War On Curiosity" (stamping out hobbyist science in order to keep kids safe.)For lots of suggested low-temp physics demonstrations click on the above link. Or, look on the web for liquid nitrogen demonstrations.Note that dry ice comes from companies listed in your local yellow pages. Some welder supply stores carry it. In Seattle, you can find it in the seafood section of QFC neighborhood grocery, and at some Fred Meyer stores. Ask for dry ice pellets rather than slabs, so you won't have to chop it up yourself..Lots more stuff at SCIENCE HOBBYIST http://amasci.com/unew.html.Note: trolls/spammers blocked immediately, zero tolerance

May 10, 2012 - Yay!(Treat your background like a movie set, a controlled environment. Supply various objects for subtle subliminal effects. Or just for troll-baiting, like "unsuccessful cherry-breaking attempt.")

May 19, 2012 - only if you want to get poisoned. (Isopropyl, especially in that concentration, is not goot for you)
Natalie Stone Says:
May 20, 2012 - Can you make ice cream with this stuff without dying?
brandon ubee Says:
May 23, 2012 - yes
wbeaty Says:
May 25, 2012 - > make ice cream with this stuff without dying?Not rubbing alcohol! And use food-grade dry ice, not the toxic oily industrial type. Maybe try 151-proof rum, and icecream mixture pre-chilled in the fridge. Or instant frozen margaritas? In some states 190-proof Everclear is legal (not WA though.)
