So, where's my time machine?
You can't see it. I can't see it, but it's here. I leave the time machine just one minute into the future.
It's here, under the trees, but it's always just one minute in front of us in time.
That's why you can't see it.
It's waiting for me.
I have a small remote control.
The control stops the time machine.
Then I wait for one minute, and the time machine is here!
Then I can go home!
