It's a blog meme. And a thing I found at my father's house.
But it looks like an angry alien.
Or a resigned squid.
Actually it is a Bob Lane Collapsible Cup.
With the help of the smart phone I identified it and made it work.
So I kept it.
It holds liquid without leaking. It's a keeper.
Why I think I'll have a need for a collapsible cup, I don't know...
