Doodle God: Rocket Scientist

Act as god of the whole world for a moment and start inventing new technologies that gradually shaped our society as we know it today. Nowadays, when the world is being shaped by technology, we are accustomed to things that our ancestors would consider as some science fiction movie. Cell phone fifty years ago? And what about 250 years ago? Or a computer? Hardly any! But let's go to the very beginning... Four basic elements and it's just up to you, how you combine them together and which other, more advanced, elements you'll find through it. Will you manage to invent super modern technologies, such as space travelling and many others? Have fun.
