🕳️ Limestone Cave: Speleothem Growth, Drip Chemistry and Echo Acoustics Lab

Walk a three-chamber limestone cave with an underground river: change soil and cave CO2, temperature and drip rate to watch a stalactite and stalagmite grow together (CaCO3 film kinetics), and clap in each hall to see and hear echoes and reverberation (Sabine/Eyring RT60 checked by particle tracing).
