Where can i get one of these? I might have a surprise for my room mate

Great tool for harrassing fires. I've seen similar time-delayed devices (blocks of ice in a mortar tube that melts over time, etc).

Cool stuff

On overcast days, everybody's confused? Cool idea though.

5 minutes walk from my home there's the only working solargun in the world:

It's a 6-pounder and you can hear it for miles. It's fully automatic except the loading so long as it is sunny weather. It was used as a clock for the castle's workers and today the last baron of Sweden lives here as well. He is a friendly man but requires anyone to adress him with sir if you do not know him on a personell level, which of course everyone does as a sign of history.

If anyone whishes to know more about this or want to have photographies just give me a shout. :D Maybe I should consider sending pics and info to acidcow.com?
