Patching a bike's tire inner tube is much easier and faster than it sounds.
You Will Need:
* An inner tube with a puncture
* A bicycle patch kit, consisting of patches, glue, and a square of sandpaper
* A bike tire pump
* A big bowl filled with water (optional)
* Towel (optional)
Using a bowl of water, run the air-filled tube through the water. Look for a stream of bubbles emanating from the tube. That's where your hole is. A good rule of thumb is to replace a tube after you've patched it three times. Bike patches are typically more durable than the tube itself.
