 supanova_gurl Apr 26, 2002 pretty good... u learn someting new everyday! curly May 05, 2002 Also he could pour the boiling water into a jug whilst holding it over his head. Thus pouring boiling water over his head. If the question said ,pouring boiling water ON TO his head then that would be different.......and stupid!!! jimmh22 May 06, 2002 the scientist could also do his experiment at extemely high altitude, which is the same general idea as creating the vacuum (user deleted) Aug 14, 2002 Go up to a high altitude and boil water without a vaccum and then pour it on your head. Call me when you get out of the hospital. I'll stick with the vaccum! mcfarfar Jan 21, 2003 what about adding Dry Ice to it? wouldnt that make it boil, or at least look like it? mcfarfar Jan 21, 2003 nevermind that would count as cooling it down cyberstar5150 Aug 04, 2006 Standard physics When vapor pressure = atmospheric pressure, the liquid comes to a boil. calmsavior Mar 12, 2007 What if he had a boil (skin) on his head precious1026 Dec 13, 2008 The problem arises with boiling "Pure" water. When we boil pure water, we don't mean to suggest Additives, such as a vaccum. I thought pouring the water Over his head and not touching his head with boiling water was better, than the old vaccum in the pot trick. Good Teaser, good fun. Great job
