DON’T EAT IT!

[House Atreides]

Well, what does it taste like? /s

[Doogle]

..pee pee

[Husker24]

I don’t think it’s all that mysterious.

[ripnbang]

A Frank Zappa songs comes to mind.

I wonder how many people’s dna would be found in that ice?

[Mount Athos]

i guess it’s probably deicing fluid icicle instead of frozen pee from the airplane lav.

Lady is pretty smart for keeping it in freezer for testing

Good book that everyone should read. Yellow Ice by I. P. Freely.

Mysterious Yellow Ice Plops Onto Roof Near Airport

When pee pee plops ...
Then one is like two.
It's yellow but(t)
It lands just like poo poo.

Sure it was yellow? Could it have a tinge of green?

[Brilliant]

Not too mysterious.

Liquids freeze at temps at 30k feet

[jmacusa]

It’s not water ice. Trust me.

[NonValueAdded]

If that happened to me, I’d be pissed.

[Yaelle]

They should have skydumped the lavs farther from the airport.

[lizma2]

Could be worse!
