In the hour after waking up, we humans are confronted with an abundance of chemicals and chemical products: Usually in a very pleasant way! The experimental lecture sheds light on the many facets of chemistry in the morning.
By breakfast, we encounter water, plastics and toothpaste, which is fine, but also acetaldehyde, furfurylthiol and sotolone (components of coffee flavouring). Surfactants, fragrances and colourings are allowed to act on the body and we try to get rid of them again with the biosolvent water.

The tongue is a very versatile organ. It helps with speaking, swallowing, chewing and many other activities in the mouth. The tongue consists of 9 different muscles, each of which can only contract, but you can still stick out your tongue. How does that work? And how does it work when a chameleon can catapult its tongue out to the length of its own body? What does a gummy bear taste like if you just put it on your tongue? Does salt always taste salty and isn't hot chilli actually bodily harm? Who can roll their tongue? And what happens when you roll an R? All in all, it's about physics, biology and chemistry in the mouth. The audience is asked to have a gummy bear and a grain of salt ready.

Everyone has eaten an egg at some point - probably indulging in the pleasure without thinking about the interesting questions and answers worth knowing that are hidden behind eggs.
The experimental lecture looks at aspects relating to eggs and answers questions such as: Why do you need a lot of water in the egg cooker for a few eggs and little water for many eggs? Why are eggs quenched? How does the egg come out of the hen? Which hens lay white eggs and which lay brown eggs? What is the colouring of brown eggs made of? How can you tell whether an egg is cooked or raw? How long does it take a chicken to produce 8g of protein for the egg? How long does it take to form the shell? Are chickens stupid or smart? And much more.
