Looks like any old memory stick, doesn't it?
And it is. It is my "to go" stick, the one that lives in my pocket (how much more convenient isn't the modern sneaker net, compared to the old floppies?). Like does the key ring, some loose change - well, you know.
Then, one day, the jeans needed a wash. And (you guessed it) I forgot about the memory stick. And the key ring.
When I took the laundry out of the machine, I found the keys. Didn't look further, and popped in the next load.
The above memory stick has survived not one, but two machine washes, the second one on 90 C. And: it works! (Perhaps I should be glad it fell out of the pocket - would it have survived the dryer?)
