My students Hanne van Uden, Lieke Hendriks and Veerle Wilms and I presented an interactive demo of a scientific experiment at Kletskoppenfestival in the library in The Hague. Around 100 children between the ages of 3 and 12 years participated and learnt about how they could ignore music in the background. See also this link for a nice report of the day at Nemo Kennislink.
