Zeanium: a website to learn chemistry
Zeanium is the platform I built for a chemistry content creator. It is a free website to learn chemistry by playing, with an interactive periodic table, games, flashcards, courses and its own community.
The idea «Make chemistry click for everyone.»
The video I made for Zeanium
I also made its promo video: the creator’s own voice, real recordings of the site and music cut to the beat of the story.
