Welcome to our new website! We wanted to make it even easier for you to dive into all the material from our experiments and activities. Every experiment since 2005 is documented with a variety of video, reports, articles and/or photos. You can find out more about each experiment in the EXPERIMENTS list (sort them by using the menu on the right) - and you can find the complete list of documentation material in the ARCHIVE. Enjoy! And please don't hesitate to let us know what you think about the site and the functions, and give us your ideas for improvements.
