Alright so 25 years ago we had stuff in BTTF2 probably jokingly inserted into the movie:
Power laces, hoverboards, flying cars (still waiting on that one), hermetically sealed Pepsi bottles (due to the Tylenol tampering scare in the 80's), micro-hydrate ovens that unshrink a pizza in 5 seconds, video fax conference calls (ok well minus the fax part, we have that NOW), keyless entry systems (thumpads), digital screens (those are still coming), floating dogwalkers, dust repellent paper (doesn't that exist somewhere?), binoculars the size of a credit card (I think these would work as a computer zooming device, probably cell phone size!), holograms, instant news (internet), and instant weather monitoring services.

The latest is we have Nike bringing out the actual power laces shoe from the movie, down to every detail.
Now what are we going to have as futuristic objects in the future FROM NOW?
Please no WAR inventions.
