So... source was the last of the most hydrophobic soil sample I had from a well known West London Poa Paradise...Originally taken early March and split into 3 horizons, this is last from top 60mm
From this 1 base sample it was split into 6 equal sub samples of 60mls each.
First is to remain Air Dried as is as the Control, next one to be flushed with just water, then a Citric Acid flush, a Chlorine Flush and the ol Brake Cleaner again to recheck its effect. Last one was a 'spare' so I just observed how it interacted with water.
60mls of soil in each one, 10mls of Citric Acid and Chlorine Shock in 100mls of water each.
Stage 1 - Each sample wetted up and stirred for 5 minutes until soil fully coated and soaked then placed on a gauze in a funnel to be flushed through with 400ml of water.
So here is just some neat 100% H2O
Next we have the ol Citric Acid, 10mls dissolved into 100mls of solution
Then we had the Chlorine Shock again, 10mls into 100mls of Flush
And finally the Brake Cleaner, OK it wasn't 100mls soak, much more difficult to get an even initial volume so just soaked it and stirred until all cover before the 'flush'
So this is them Flushed out, stage 2 is to let them naturally Air Dry then repeat the Timed Droplet Test
H2O
Citric Acid
Chlorine
Solvent
And finally the 'spare' sample, a crap video of it being wetted and then agitated to show how much this stuff loves water... not
Here's the wet
And the agitate
OK my apologies.... it the seems that the
Failed on this occasion... Tsk another call to Customer Services...
Right..... See you when they are dry...
