Lynn tested the effect of different types of cooking oil on the amount of time it takes for a drop of water to fall through a container of oil. He poured the same amount of canola oil, olive oil, and coconut oil each into three different clear containers. He had his partner start a stopwatch at the exact moment he placed a water drop onto the surface of each oil. He recorded the time it took for each water drop to fall through the oil and analyzed the data. Which variable must Lynn hold constant in order to accurately investigate the effect of different cooking oils on a water drop falling through the oil?

Idk

Explanation:

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
