@ulysse3329 Thanks a lot, nobody have measured the temperature yesterday, but it was around 5-6 degrees of Celcius. The temperature of air might be zero close to the ground, because we have noticed frost grass, first time that year. The longest time may be around 13 minutes. (in my humble opinion so long may be harmful, but... they still doing it...)
Nice video! What was the temperature of the water and the air? What was the longest time in water?
