This event is happening 16-17 Sep 2017 and I’ve decided to go as I was already planning a holiday in Slovenia around then.
Anyone else interested to get a good GOSH crowd there? Maker Faire is combined with a Science Picnic Village “a special area where happy scientists and passionate explainers will engage a public mostly of kids and young people, showing the entertaining and creative side of science with various hands-on activities, shows, labs and demos.”
Also note from the website:
The ICTP is offering free accommodation at the campus guesthouses to the makers coming from outside Trieste. The availability of rooms in limited, so we invite you to send your applications as soon as possible.
Applications for demos, talks, exhibits etc end on 6 Aug but might be worth following the advice above!
