What current product do you think would baffle people in 100 years?

Plastic!

What is Astroglide?........I think interior house walls...they will be obsolete with nano-techonolgy...you'll be able to move around invisible walls in your house like you do the picture on the wall. Included will be sound proofing from one room to the next also. color choice of several colors or patterns, what might be one big room one day could be two rooms the next or vice versa. instant wall for instant overnight bedroom... the possibilites will be limitless. I am also understanding there will be one wall tv sets/communication centers with this, which you will be able to make any size TV/movie screen you'd like. You can also make half walls if you'd like. It will revlutionize the term "house decor" and then some. that is provided things go along as they are inteneded, they already have this, just tuning up the fine lines of it beffore its released into the public. An world of the future.
