This is one of those motivational posters that should be taken very seriously. Here we have Darth Vader taking a sample of our Earth’s water for detailed analysis.
It’s obvious that he will use the sample to turn our oceans against us in his plan to conquer Earth.
Why else would he be doing this? Probably not to see if he can go for a swim without his mask. Or maybe they’re short of salt on the death star and Vader plans to get some by evaporating seawater.
May be coolant for his cool suit
It gets hot in there
