Discover and experience glass – an exciting experimental trip which takes you through the glass world. We have set up more than 70 experiments for you to tinker with. You can play musical glass instruments, marvel at interesting optical effects, find out about our ultra-modern glass applications, or play traditional and nostalgic games with glass marbles in the Glasi Park. Children will be enchanted by the water fountains on the lake, the giant quartz sand pit, and the 7-metre-high marble run tower with slide.
