Air powered cars are (or will soon be) real in India: https://www.drivespark.com/four-wheelers/2017/tata-motors-air-powered-car-airpod-launch-2020/articlecontent-pf61534-020628.html
I used something like that a long time ago. It was called “glass wick” and came in a yellow plastic container similar to a Chap Stick. Under the cover was a cloth infused with the product. It improved lenses very similar to what you’re describing.
Unfortunately, I haven’t seen Glass Wick in stores for a long time.
Yes they do. Just like wearing a scarf. They trap your exhalations near your face causing your glasses to fog up (and when it’s really cold, frost up).
These days, there are some incredibly good vegi-burgers. A few years ago, those that attempted to be fake meat (e.g. Boca) were terrible and the rest (e.g. Gardenburger) made no attempt to taste like real meat. But today you can get Impossible and Beyond burgers, which, while not perfect copies, taste really great. And they’re even available from restaurant chains (e.g. Burger King’s Impossible Whopper and Dunkin Donuts’ breakfast sandwiches with Beyond saussage.)
It’s called having an appetizer. :-)
