last week a big black tub landed on the deck…

a few days later, in the evening, it got filled up with water…

then a cover went over it… and a heater to keep the temperature at 5° Celsius was added…

now, after a shower, someone uncovers the tub and sits in it for 3 minutes, which seems like a long time, lol…

this is what I spotted this morning;-)…

I am going to give it a try on a Sunday morning… wish me luck…
