ELI5: What is Heisenberg's uncertainty principle in layman's terms?

EDIT: Past the basics i.e. "The more we know about something's speed, the less we know about its location."

In the simplest terms, anything we do to try and detect the location of a particle will change its speed.  In the same way, anything we do to try and measure its speed will change its location.  It's a matter of measurement and sensing sciences, which we cannot (at least yet) surmount.  Heisenberg's theory is that it is impossible to know both at once.
