|Kids activity at Torino MMF 2016|
I had booked a total of 4 seats together with two more children, but when we came (a bit late I must admit), the lab volunteers could take only one child because they had run out of CR2032 battery holders. Too bad, because the two boy-friends were willing to try! On the other hand the staff had conductive ink to spare.
