How Van der Waals Forces Power the Coin Volcano’s Microscopic Explosion
The Coin Volcano—a dazzling display of expanding gas and compressed material—reveals a hidden truth: macroscopic spectacle emerges from atomic-scale interactions. Beneath the visible eruption lies a world governed not by brute strength, but by subtle electromagnetic whispers—Van der Waals forces. These invisible interactions, though individually weak, collectively orchestrate dramatic transformations. How do such faint forces drive visible explosions? And what can this phenomenon teach us about emergence, measurement, and the language of structure across scales? Foundations: What Are Van der Waals Forces? Van der Waals forces are weak, short-range intermolecular…
