Congratulations, Jim! That is exciting!
By the way, if I was into yo-yo's I think I could build a giant one that would work much better than the one on the video. But I only see giant tops in my future
I loved the Palais de la Découverte with its old-fashion science demonstrations, much more than the more modern and bigger La Cité des Sciences et de l'Industrie with its pretty displays. I will definitely visit it again.
