Duckweed

In infrared, duckweed is white* and ducks are invisible**.


* Well, the sensor interprets it as “white”. Colours, even white, are tricky when you’re talking about non-visible light.

**Not really.

Duckweed is always lovely, but this is SOMETHING ELSE. It looks like fancy lacework.

I am sad that the ducks are not actually invisible in infrared.
