D2o Memes

The perfect chemistry joke doesn't exi— Oh wait, here it is! This meme plays on the notation for water (H₂O) versus heavy water (D₂O), where deuterium replaces hydrogen. The fitness model represents regular water, while the... robust gentleman represents what happens when you swap those hydrogens for their heavier isotope. Chemistry nerds will appreciate that deuterium is literally just hydrogen with extra neutron weight. The perfect visual metaphor for why chemists shouldn't skip isotope day at the gym.
