Best do that with something that hides the taste well. Maybe create a drink so aggressive that it might as well be a cleaning product. Just add some caramel to paint the whole thing black and you’re good to go. People will love you coca product.

Such thoughts can be very Satisfactory indeed.

My C++ teacher taught me to be against unions. He made everything class based instead.

This is terrible programming advice.

Considering that portals are quite literally linked in a spatial manner, it would make sense that they physically cannot move independantly. Moving the orange portal would also move the blue portal. Or from a different perspective: the portals are always fixed in space, but their surrounds can move.

But that does not make the question shown here untestable. It just means the output portal will have a velocity of it’s own.

How to test: place 2 portals next to each other on a wall. Then apply propulsion gel in front of the orange portal. And finally move yourself at high speed through the orange portal.

If your speed is unchanged after exiting the blue portal, but your velocity has been inverted with respect to the direction that the wall is facing, we can conclude option B must hold.

For shits amd giggles, I put a couple of industrial 10W fans in my PC once. That probably still made more noise than this. It also created so much overpressure that I could feel air escaping the tower from every little hole or crack. You could hold a piece of paper to the side of the pc, and see it moving because of the air escaping between the side panel and the main hull.

But if these are normal fans (max maybe 1,5W), then the amount of power drawn will be the same as a couple of hardrives.
