Abstract

Descartes` theory has the conclusion that rainbow can be observed if the observer looks at a curtain of rain drops and behind him/her Sun is at 42 degrees in the clear sky. We realized an installation that produces a curtain of water drops that is very similar with the natural conditions. Several simple STEM (Science, Technology, Engineering and Mathematics) projects on Science Education as examples of creative activities can be realized. Also this result has touristic importance.
