This year the explorhino in my home town Aalen has its 10-year anniversary and I attended it's bug birthday party yesterday. The explorhino Aalen has the goal to teach kids and young adults how much fun science can be. Two years ago they even opened a small science center.
At the birthday, party science entertainer Joachim Hecker held a beautiful and super fun science show for kids. Afterwards the kids (and parents) could discover the world of science at different small tables with experiments. I had a lot of fun supervising and helping kids to figure out why the balloon shrinks once you dip it in liquid nitrogen.
