I took Electricity in 4H one year and made for my project a heavy-duty extension cord for my mother's iron. Her washer, dryer and iron/ironing board were in the basement. The extension card was plugged into an outlet between the floor joists above, and had a large cup hook above the ironing board to keep the extension cord out of the way when not in use.
I estimate that this was in 1962 and that I was eleven year's old. Mama used this set-up until she moved into an assisted living facility 4 years ago. The new occupants of the house are still using it.
It's good to know how useful this idea was and how long it has lasted.
