Licking the index finger

I was having a group discussion with my ACT team. We were struggling with a calculation when a Dutch teammate said: ‘If we can't figure it out, we can just do this.’ Then he quickly licked his index finger and lifted it up in the air, as if he was pointing at the ceiling.

Seeing that the other international student in our group and I were both quite confused, he explained what he meant. The gesture of licking the index finger and raising it in the air means ‘making a rough estimation’. It has to do with the typical windy weather in the Netherlands. In the past, when the Dutch wanted to know which direction the wind was blowing from, they would lick their index fingers and raise them. The wet finger would feel coldest and dry fastest on the side the wind was coming from, and so a rough estimation of the wind direction could be made. Over time, the meaning of this action extended beyond estimating the wind direction to any kind of ‘guesstimation’.

Of course wind direction in The Netherlands is no longer measured in this way nowadays, either due to the huge uncertainty of this method or the widespread use of wind vanes. But it's still an interesting example of how even a small gesture can have a deep bond with a country, its climate and its people.
