Bikini Bottom was named for Bikini Atoll where the US conducted nuclear tests from 1946 – 1958, which is why all the explosions from SpongeBob look like nuclear explosions.

While SpongeBob doesn’t quite depict the horrors of nuclear testing, its inspiration does.

SpongeBob’s home, Bikini Bottom, was named for Bikini Atoll where the U.S. conducted nuclear tests from 1946 to 1958. References to the destructive nuclear tests are littered throughout the show, ranging from a magazine “Toxic Waste Monthly” to an indiscreet island featured in the introduction to every episode. Even more blatant are all the explosions in the show, which mirror the infamous nuclear mushroom clouds. One episode even features a town called “Rock Bottom” that mimics the crater created on the ocean floor during one of the nuclear bomb tests.

SpongeBob got to this nuclear adjacent crater accidentally, and was then left stranded beca… Continue Reading (4 minute read)

    Also explains why they all have arms, legs, and can talk

    In addition, a nuclear explosion is what most people think of when they picture an explosion.

    Or… when people think of “big explosion”, they think of explosions with mushroom clouds (which aren’t necessarily nuclear, anyway).

    Don’t do all “big cartoon explosions” look like that?

    Also, I am not a physicist, but I thought it isn’t the “nuclear” part that makes the mushroom shape, but the size/energy of the explosion. So any big enough explosion gives you a mushroom cloud, no matter if nuclear or not?

    I mean, it’s also a pun. “Bikini Bottom” being the swimwear.

    The Bikini swimsuit was named after the Atoll by it’s inventor Jacques Helm, when he heard of the nuclear test. So Bikini Bottom could be read either way

    Yeah I went down a SpongeBob rabbit hole once or twice. I have since learned a lot about the Marshall Islands and our continued streak of destroying ecosystems for fun and profit and to feel manlier than the Soviets.

    It’s literally in a bikini bottom, as in the bottom half of a two piece swimsuit. Look at the background “sky” in SpongeBob, it has floral print…

    It’s called Bikini Bottom because it’s a pun and it is actually located beneath the bikini atoll – there is no real link to nuclear tests mentioned anywhere in the show’s wiki and no reference made to it anywhere in the show.

    The pun is kinda self-referential since the bikini is named after the atomic tests on the atoll, referencing it’s bombshell effect on the fashion world at the time (it was so scandalous they had to hire nude dancers to show it, since no model wanted to wear it)

    Bikini atoll has the best preserved natural environment in the Pacific today, because all the inhabitants were removed and it has been declared off-limits for human visitation since the 1950s.

    There’s a force that causes far more devastation than nuclear explosions, that’s the presence of human beings.
