Hey, imagine a yeast cell as a tiny particle stuck behind a sugary wall. In quantum physics, particles can tunnel through barriers even if they don’t have enough energy classically. But yeast is macroscopic, way too heavy for its wavefunction to spread enough for tunneling to matter. In practice, the cell just diffuses or pushes its way out through normal biochemical processes. So while the idea is fun, tunneling won’t speed up your cookie‑cracking adventure. Just keep an eye on the temperature and the dough will do its own thing.
