We had Fun at the University’s Open House
On Saturday, we displayed some experiments at the open house of the university. The kids that I’ve seen were all very enthusiastic about water. Building a dam is always more exciting than watching how a river flows. That’s how it goes. 
After too many dams were built, and no more river was to be seen, we started the syphon, to clean everything up. See video below.
So, where’s the video?
Good question, Thomas! I had uploaded it. Maybe it was too big, and the server refused to accept it. Maybe I have to get a youTube account? :-0
