Nuclear engineers getting existential about H₂O! Without water to slow down those hyperactive neutrons, our reactors would be like teenagers without WiFi—completely uncontrollable! Water is basically the bouncer at neutron club, telling those zippy particles to "chill out, bro." Next time you drink water, remember you're sipping on what keeps nuclear reactors from throwing temper tantrums. Truly the unsung hero of fission!
