Still no luck with the ice-lock. I put on the balcony for the night (there was -3) and then in the fridge (right on the ice) for the day. Checked in the evening – water. Leaving it for another night made no sense (+3), but I simply forgot it outside. I hope nobody found it 😉
Since I had no time lock I had to choose another method. Crawling and difficult release. And I dropped a knife in the corridor.
“What now?” That took me quite a while. I dropped everything I took with me on the bed (the stuff covered it all). Still no ideas… Eventually, after multiple picking up one thing after another, at 3AM in the morning I decided on the plan for the night.
