BANG!


 
The picture says it all.


We had a free pie this weekend, courtesy of a bag full of Blackberries
from around and about these parts and a box of apples from a friends
tree at their stables.

And with pie must come custard!

But it got me to thinking about the explosive nature of custard.

Well, not the custard so much as the cornflour in it that thickens the custard
on heating.  Like any fine sifted flour it has ignitive properties.

If you have a flour mill anywhere near you try getting close enough to take a peek.
You'll find warning signs all over the place and a massive earthing strap around the
building to stop any build up of static electricity inside.  Contractors that get called to
work inside the buildings are specially vetted and have to use special tools that
won't spark (plastic or rubber covered spanners and hammers etc - same as in
an oil refinery).

Just imagine the bang from one of these 3Kg commercial custard bags emptied
into a large steel drum!? Now there's a thought for another weekend's experiments!
                          Weird but true!
