Nitrous Bottles

To keep the nitrous bottle within a safe functioning range, particular temperature and internal pressure standards are required. The bottles' internal pressure increases as they warm up (just as a tyre would on a sunny day). For this reason, you should never keep a bottle heater on for an extended amount of time, and you should never, ever use a torch to warm the bottle (even worse, this also weakens the structure of the bottle). However, as you may imagine, a car can get extremely hot inside on a day with a high of 90 degrees with the sun.
