EDIT: This offer has been steamed to death.
All of my scientific knowledge came from years of watching Bill Nye the Science Guy as a kid, so I may not be an expert in this field. However, I'm pretty sure it's impossible to simultaneously freeze and steam something without it, well, turn into something you'd throw away rather than save. Well who knows, maybe thesewill prove me wrong. That's really not as laudable a feat as it may sound though. My dog easily shows me up a dozen times a day.
