|Everyone's a nitrogen expert!|
Imagine this! Each ordinary air tank filling consists of almost 80% pure nitrogen. So, as there is so much of it in each tank ... shouldn't each one of you also be a nitrogen expert for safety reasons?!
Thanks to the absolutely fabulous PAYDI this is no more an issue. Thanks to all those blabla-aware projects, we are now able to train you to become a nitrogen expert.
And after the show, pardon, training, you can easily show off your newly earned ignorance to all your wannabe friends with this card. Acquiring knowledge cards is really so easy in the age of credit cards.
PS: Many thanks to Ludwig Nachtmann for this shot he did near Île d'Or next to Le Dramont (83/F).
