From my childhood , Ive been fascinated by this subject, and its fired my imagination and interests which has lead me to where I am today, .. much of what we know centres around our unterstanding of chemistry which has lead us to produce so many of the products we use on a day to day basis and indeed our boats and what powers them .. Ive always found the science fascinating .. its an hour long and I suggest you get a beer or coffee and enjoy ..
how not to put out fires was interesting half way through
