Another bl##dy cold day at chez moi - around 3 or 4 degrees as I type this.
Have started to put together an Oxalic Acid evaporator: as I've been drilling 22mm holes in all me hives (to use wine cork stoppers), it would seem to make sense to also use a 22mm copper tube to get the gas in. However, the girls have coated the inside of the holes, so a 22 pipe doesn't quite fit.
So - assuming the girls would be tightly clustered, I fitted a brace with a 22mm hole-cutter in order to clear the hole, and gave it a couple of quick turns. One girl came whizzing out to complain (so she obviously wasn't clustered) only to make a quick circuit before scampering back through the hole a lot faster than she'd come out.
I could almost hear her muttering "Sod flying in this weather" ... or was it ... "Oh no, not HIM again".
