Bang! HISSSSSSSSSSSSSSSSSSSSSSSSSSSSS!
Odd, no whoosh-whoosh-whoosh as the puncture spun around.
And the prolonged hiss stopped as soon as I stopped.
Well, a Slime tube can seal things like that.
But the front tire feels fine. Maybe it's the back tire? No, both
tires are fine.
Hmmm . . . Flip bike upside-down, peer more closely at tires. Nope,
both tires are fine.
Idly spin rear tire--nothing.
Idly spin front tire--HISSSSSSSSSSSSSSSSSSSSSS!
A dry branch goes bang! when it breaks under the front tire.
A dry leaf trapped just right between fork legs and the brake arms
makes a really impressive hissing noise if the tire just barely rubs
it.
Just don't do what a friend did and try to pull that leaf out while
riding -- he touched the tire, which drew his finger in. He was lucky to
get away with only a broken finger and collarbone. It's one of the first
things off-roaders learn not to do.

Foosh!
No doubt about this puncture, flat as a pancake in an instant.
A car ran over someone's purple sunglasses, leaving a sharp and
hard-to-see lens fragment, which my front tire flipped up to greet my

My strangest encounter was with a CD jewel case lid. I was cornering and
didn't see it in the twilight and my front tire somehow adhered to it
enough to skate a couple of feet. I didn't go down (barely).
Made me long for a simple goathead. Reminded why I carry tire boots
and a rolled-up spare tire.
I stopped to fix a flat on my way home from riding a double century
(with no flats) and found a nail (concrete) through tire, tube, rim
strip and double wall rim, the point extending perhaps 1/4" above the
spoke bed.
I got a flat in the exact same point on a weekly club ride four weeks in
a row. I turned out there was a nearly invisible wire that took
precisely that long to nibble through the tube.
