4 Real Inventions Inspired by Science Fiction

Where science fiction becomes science fact - that is the place Hank is exploring in today's episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser. Blast off for knowledge!
