Which way the wind blows

Some days ago my brothers payed us a visit here in Berlin and they are both crazy aeromodelers in their free time and persuaded me to visit the Technisches Museum Berlin with them. They wanted to see the Aerospace section, I mainly wanted to play with things. And I found this funny wind channel! With the background it looks like we're having a stiff breeze on the seaside. Fun!

Today is our first day on our first farm in Italy. Pictures will be posted soon!
