Science brain teasers require understanding of the physical or biological world and the laws that govern it.
A clever scientist in his lab can bring pure water to a vigorous boil, then immediately pour the water over his head without scalding himself. How does he do it?
Note: He does not cool the water down and he has no protective clothing whatsoever.
HintThere are two ways to boil water. One is to heat it to 212 degrees Fahrenheit. What is the other?
He can apply a vacuum to a container of water. The water will boil but will remain at room temperature. He can then quickly relieve the vacuum and pour the water over his head without worry of scalding himself.

| 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!!!|

|the scientist could also do his experiment at extemely high altitude, which is the same general idea as creating the vacuum|

|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!|

|what about adding Dry Ice to it? wouldnt that make it boil, or at least look like it?|

that would count as cooling it down

|Standard physics |
When vapor pressure = atmospheric pressure, the liquid comes to a boil.

|What if he had a boil (skin) on his head|

| 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 |
