The answer is DYNOMITE!


As usual, I have been remiss by not commenting on the Blog...I have enjoyed these blog entries from your Scandinavian adventure immensely, Susan and Rob. What a treat for all of us out here in Blog-dom to vicariously go along for the ride! Each day, I have looked forward to hearing about your adventures. I look forward to seeing you in person very soon now...

Delores Herzberg

In 1866 the Swedish engineer Alfred Nobel made practical use of nitroglycerin in his invention of dynamite. He found that when nitoglycerin is mixed with an earthy substance (kieselguhr) it is stabilized and can be used with reasonable safety.

Delores Herzberg

Actually the nitroglycerin is made by reacting glycerol and concentrated nitric acid, this yields glyceryl trinitrate, better known as nitroglycerin. Not to be confused with trinitrotoluene, aka TNT.

Delores Herzberg

Since the reaction between glycerol and nitric acid does not take place readily unless the water is removed by a dehydrating agent it is customary to use concentrated sulfuric acid as the dehydrating agent.

Delores Herzberg

However, one should not attempt this reaction at home. In the unlikely event it does not explode one might find a visitor at your door wearing an ATF jacket!

Delores Herzberg

A little known but interesting fact about nitroglycerin is that it requires no oxidizing agent to explode. It has within it own molecules all the oxygen needed to bring about the formation of gaseous products, CO2 nirogen, oxtgen, and steam. These gasses in their effort to occupy a volume many thousand times greater than that occupied by the nitroglycerin, exert such a tremendous pressure that a shattering explosion is the result. Needless to say we now know that Nobel was a very cool chemist of which there are many in our own family. Remember there will be a quiz on this later in the week.


What else can I say? I mean really...I think Delores said it all. Have safe enjoyable travels and a smooth transition to lunch in the sun. Zanny

For a sunshine girl, I would not enjoy all that darkness! What is it like in the summertime? I have so enjoyed your blogs, that it is kind of sad to have your trip come to an end! It will be great to have you back home, though. I am sure Tessa and Sam will agree.
See you later, weather permitting for you and for us.



Having been scooped by Mom? on he dynamite issue, I'll have to bow out of the running for family chemist of the week. I haven't heard kieselguhr mentioned since last week's lunch menu here at work.....

Glad you made it back on time and had a great trip.
