Educate yourself
For instance, by opening a few wiki pages, youtube videos and the like and educating ourselves about how those miracle workers are keeping our world clean. Don't you just get goosebumps thinking about it? The tons upon tons of water (and shit!) gently nudged by gravity along it's very-precisely-sloping path, on its way to the sea (hopefully with a detour through a filtration plant on the way).
Give thanks
If you know anyone working in the field - say a sincere thank you, ask them about interesting anecdotes from their work and bring them over to the next pastafarian meetup!
The most sincere form of thank giving in Pastafarianism is actually buying them a beer!
Have fun
Get a few friends together, have a weird conversation and when the beers you've consumed eventually need to leave your body - meditate on their onward journey and reflect on the luxury of not having to deal with a chamber pot or an outhouse!
