Welcome to my channel. My name is Vitaly, and I love science!
My task is to inspire children to explore the interesting science. Here you will find lots of unexpected experiments; crafts improvised with minimal costs; interesting observations, the secrets of unusual phenomena, as well as long-term projects!
