Time traveling. The concept of it is seductive. Imagine if you could go back in time to change the events of your life. We've all imagined it. Sadly, and also good enough, it isn't possible. But some people aren't giving up on the idea.

Here's a trailer for Jay Cheel's documentary "How to Build a Time Machine" and it is about two men who talk about undertaking time travel.
When Rob Niosi decided to build a full scale replica of the time machine prop from George Pal's adaptation of H.G. Wells' novella 'The Time Machine', he had no idea what he was getting himself into. The three month project is now in its eleventh year, and he's not sure it will ever end. His perfectionist attitude and obsessive nature — cultivated by years of detail oriented, time consuming work as a stop-motion animator — has elevated his machine from prop replica to a true work of art. His goal? To capture the impression he had as a kid when he first laid eyes on the beautiful machine.

When Ronald Mallett was a young boy, his Father died unexpectedly of a heart attack. This event turned his world upside down. He became ostracized from his friends and family and found solace in science fiction. It was H.G. W ells' The Time Machine that inspired Ron to pursue a career in physics. His goal? To build a time machine so he could go back and save his Father.
