@Cmonmyboi@physicsJ Yes, third-reflection rainbows emerge from the raindrops in roughly the same direction as the incident sunlight. But they are faint and diffuse and hard to see against the sun.
@MicrobiomDigest Looks like the same image of the surrounding plate was used for all of these. The random bits of substrate and light reflections appear unexpectedly identical.

@Rainmaker1973 That’s dangerous advice; you might want to delete this. The tap test is a way to check for maggots. It does *not* mean the mushroom is “very likely” edible.
Most mushrooms are not edible (that round brown one at the end).
And some are poisonous (the red and white amanita).
@timeout2575 @MicrobiomDigest@Harvard What I’m seeing is on the B negative control image. If you scan along its top edge, there are three small gray triangles, above the marks for 2 mm, 9 mm and 10 mm. That apparent repetition is what I’m referring to.
@DrJenGunter “there is no confirmed date for when other visa-exempt nationalities will need an ETA for the UK.” And the list includes the US.
I’m not sure how they could have made that page more confusing.
