Blowing Bubbles

Can anyone tell me more about the 'blowing bubbles' test to confirm well-dried firewood.?  I have seen two wonderful videos on this but I cannot get the same effect.

 

I had some ash logs which were less than well-seasoned and put them in an oven at 100 degrees C for 24 hours.  At the end of that time, and when cold, they passed every test for dryness:  substantial loss of weight, radial cracks, bark lifting a little, clacking sound when knocked together, previous resinous smell gone - and moisture meter reading at 10%.  (I've only measured the moisture externally for the time being, with a pin meter) .

 

But when I try the washing up liquid test, I only get one or two tiny bubbles after blowing very hard  -  nothing like the videos showing apparently effortless blowing with a thick layer of bubbles emerging at the end of the log.

 

Any thoughts gratefully received!

The only video I have seen is the Aduro stove one at 1.24 minutes in

Have you tried setting them alight?

It's quite apparent when wood is wet.

In one of the vids the guy demonstrated the dryness of sub 18% and over 25% (I believe) all from blowing bubbles, not sure how accurate that but if its correct to any degree is seems far quicker than setting up a wee camp fire whenever you wanna check it out.

Alright petal...

You can get a moisture metre for not many quids. 

I know that chip boxes in tree trucks get pissed in, a lot.
I'd be reticent to be putting my lips on any logs, but each to their own.
