What do you use now that will someday be in a museum?

 This treadle sewing machine was woman-powered.  It just sewed nice straight seams. ..no gimicks.

The pitcher and basin were usually made of ceramic.  An industry which provided bathing facilities for thousands of people before they got running water and a bathroom!

If I look around me to see what might be worthy of a museum in 100 or 200 years, I hope these fluorescent light bulbs will be there...and of course some laptop or iPad. An air conditioner/heater has made my life much better.  How about a microwave? I think a pop-up umbrella is pretty nifty too.
