Museum Boerhaave in Leiden is a museum of history of science. The museum was commissioned over 100 years ago. This history is represented by a variety of artifacts: from the reconstruction of the famous anatomical theater of the local university, various astronomical instruments, old surgical instruments to electromagnets and electron microscopes, and spying insects with built-in microcontrollers.
And finally Naturalis, where I came across an exhibition about organisms that are definitely poisonous. At the start a king cobra (seriously, it is a large animal…), but also a stuffed lori and a castor oil plant (the one with ricin). The coots that swim in the moat surrounding the building with really bald chicks certainly do not realize what’s going on inside.
