Alcohol does change the surface tension so foaming will be different. Ever seen a security guard shake someone's water bottle to check if it's really water?
The thing that makes beer foam stay there is the protein content. Yeast contributes some, but it's also in the grain. The foam should be less different if you compared something filtered like Heineken and Heineken 0.0.
As well as the arrows, the buttons are just positioned intuitively most of the time. We usually get two perpendicular kerb ramps rather than a diagonal one pointing at the centre of the intersection. The button for the crossing you want is the one closest to you or facing you when you're waiting at the intended ramp.
The button gets mounted on its own post if there's not a traffic light pole in the right place to piggyback off.
Traditional masonry construction has the same results in terms of thermal mass. More so, if it's denser and thicker. With the right shading and ventilation it's useful for both temperature extremes. See vernacular architecture in warmer/more extreme climates, or what Federation Square in Melbourne achieves with concrete:
Considering active heating/cooling as well as passive, the more thermal mass we have in buildings, the better they can act as thermal batteries for surplus renewable energy.
With few exceptions, your cooking oil would have to be smoking profusely before the pan is hot enough to damage silicone. At that point it's not quite hot enough to ruin the Teflon either.
To some extent, the forced downtime is a benefit. Instantly refeullable vehicles enable fatigued driving. It's not even healthy to be sitting for that long as a passenger.
Self-powered evaporative air conditioning is an ancient technology.
Air conditioning as we understand and use it today is a gold-plated band-aid over bad design. It's so entrenched you almost can't get a house built any other way.
South Australia, which generated 60% of its electricity with renewables last year, is installing synchronous condensers to provide some kind of grid stabilisation. (The current conservative government is aiming for net 100% renewables by 2030 and 500% by 2050.)
The virus can't "continue from where it left off" if there's nobody left in the country infected by it.
If it turns out there were a few infections left, or one slipped through quarantine for arriving travellers, the health system has enough capacity to perform testing for anyone with even mild symptoms, and comprehensively contact trace.
