Thanks for reminding me of a time in my life when I built a time machine, made from scrap lumber leftover after a remodeling project. I used my allowance purchasing switches, colorful wire and any cheap electronic gizmo that looked interesting. I hung it all on my crudely constructed box. Visiting adults to my attic were often fascinated by its authenticity. It worked mostly by imagination, mine. I had a lot of fun with that project and it may be why I believe I am a writer today.
