Description
Do you think nobody lives in pure water? Even a crystal-clear drop is full of tiny creatures. Are they really primitive? They have complicated lifestyles of their own — some look threatening, others at least funny. They live almost in harmony, though predators do exist among them, and so do the more peaceful ones.
Children can examine the entire microworld in detail without special equipment — all they need is a phone or tablet. Meet these amazing creatures on the pages of this book.
It isn’t magic — it’s augmented reality. Download the free DEVAR app on a smartphone or tablet, activate the book, and become the hero of an exciting adventure. The story begins on the page.
Note: The free DEVAR app is geographically restricted and can be used only in Sri Lanka.
