Mondovi, Italy, “land of hot hair balloons”

Giorgia, a young girl of our class is now very passionate about balloons, as well as her mates. She asked her mum to take her to Mondovi, a town located 35 km form the school (it’sin the region of Piemonte, Northern Italy). In Mondovi, on the weekend of 4th-5th-6th January there was the 31st Festival of Hot Hair balloons.

She took many pictures and spent a lovely day with her family!

The attached video is from Youtube: the balloons “dance”with the music of the Queen. Fantastic!
