I thoght this poem was rather appropriate, right now, as we are doing science fair at school.
Unfortunatly, my project isn't as spectacular as a time machine!

My project for the Science Fair
was absolutely cool.
I built myself a time machine
and showed it off at school.

Inventing it was not too hard;
I had a little aid.
My future self came back in time
and showed me how they're made.
