Why Are Snorkels So Short?

The video explores the limitations of snorkel length due to air pressure, lung capacity, and resistance. It explains why snorkels can't be too long, as water pressure makes breathing difficult, and longer snorkels trap exhaled air, leading to oxygen depletion. The video also discusses the inconvenience of maneuvering with a long snorkel and the buoyant force that makes it harder to keep the snorkel submerged. Ultimately, a safe snorkel length is around 35 cm, and for deeper dives, scuba gear is recommended.

What are the main reasons why the longest working snorkel is shorter than expected?

Explain how water pressure affects the ability to breathe through a snorkel.

What happens if a snorkel has a volume greater than the lungs?

Discuss the implications of using a longer snorkel in terms of resistance and buoyancy.
