Nina's Little Universe is a handmade, interactive science world I built for my five year old daughter. Children spin Earth to discover day and night, explore Moon phases and eclipses, experiment with light, and meet planets through touch-driven missions. It's bilingual in English and Albanian, free, and requires no account. What began as a personal project for Nina is now being used in schools, helping children learn by touching, testing, and discovering instead of passively watching.
