Colin, interesting !
I've always preferred brushes in the 1st filter stage for silt/sediment separation but are not the 1st chambers of ammonites generally filled with the same ?
REVOLUTIONARY !
No.66: Guido Fawkes' commemorative pyrotechnics
Whilst on the subject of revolutions, I thought it appropriate to insert no.66,
whilst also saving Tony (our gracious & benevolent leader
) a few cents off his web hosting bill.
Pack enough solid propellent & iron filings into a
Cleoniceras Besairei, drill out the centre with your Dremel (mine's a Draper as I'm of low caste). Nail to a suitable post nearby, light the blue touch paper & celebrate the barbaric death of Guido Fawkes & his chums who dared to attempt what most Brits are thinking !!
Here we see the diminutive Guido being presented to King James I prior to his extensive interrogation on the rack whereby he achieved a reasonably normal stature.
This lead to the 1st reported use of the phrase
"growing pains" also known in the 17th century as
"Fawkes' ache" which was also used as a toast by those who supported the cause after poor Guido's demise.
Apparently, the
Wright brothers assisted in the gunpowder plot but I'm afraid that suggestion is quite preposterous !
