Fixing Punctures / Puncture Repair / Exploding Tubes

The glue often cures if you roll the tube it comes in, it creates tiny holes at the creases which allow air in, the lid doesn't usually let air in. Keep your tube flat is the moral of the story.

The lid often appeared to be coated in glue anyway but it did seem like a logical place for air to get in. Thinking about it, I do squish the tube usually so maybe it wasn't the lid failing after all. Stupid feeble glue tubes!
