If you can swap a tube, you can fix one, you need, glue, patches, a piece of fine sand paper, bucket of water, an old rag, a pump. I collect up a few, and fix them at once.

Take the first one, add air, until it's about twice normal size, push it into the bucket a short piece at a time, until you see bubbles rushing out, put your thumb over the hole, dry off that section of tube, rough up an area of about 2 times the size of your patch, and cover the roughed up area with glue, put it to the side, and get the rest to this same condition, it takes about 10 minutes, to dry. Apply the patch, glue side down to the glue area on the tube, add a nice heavy weight, and do the rest to this same point. Give them about 15 minutes to set up. Use the water to make sure your patch is air proof. Dry off, let out all the air, and fold it up. Put it in a tube box or in a heavy duty zipper style plastic bag, your done.
