When I was a kid, my dad always made a big deal out of having to put chains back on bike gears or repair punctured tubes. I know it's not much fun to be hauled out of your recliner to fix a bike, but now that I know how to do both of those things myself, I can't help but wonder: Why didn't he just teach us how to do it ourselves so we didn't have to bother him next time? (I suspect he enjoyed being the fixer but just acted disgruntled so we didn't know he was enjoying it.)

I took off one side of the tire, pulled the tube out, aired it up, and could hear air escaping from the hole right away. Result! So I cleaned up the area around the hole, put on a patch, and replaced the tube. I even remembered to feel around the inside of the tire and find the pointy culprit-- it looked like a broken staple-- before I put the tire back in place, and aired the whole shebang back up. Done.
Next morning I realised, because my tire was flat again, that I hadn't put the inflated tube in water to find if there were any more holes. Oops. So, I aired up the tube nice and big like my coworkers had taught me, stuck it in a sink full of water, and found two more very small holes. No wonder I hadn't noticed them before.
Two patches later, and I put the tire back together and aired it up once more. I'm happy to say that the patches are still holding. Even still, I'm going to need a new tube. And also a new patch kit.
Have you ever changed a bike tire? When did you learn how to do it?
