Simon Lake's experimental submarine salvaging tube in New York Harbor

The video tutorial discusses the development of a submarine salvager designed to enhance the capabilities of divers. It aims to allow divers to operate in stronger currents and at greater depths than previously possible.

What is the primary objective of building the submarine salvager?

• To enable divers to work in stronger currents and at greater depths

• To improve underwater photography

• To explore underwater caves

• To increase the speed of underwater travel

How does the submarine salvager assist divers?

• By reducing the need for oxygen tanks

• By providing better lighting

• By offering more comfortable seating

• By allowing them to work in stronger currents

What challenge does the salvager help overcome for divers?

• Lack of underwater maps

• Limited visibility

• Communication barriers

• Strong underwater currents

What new capability does the salvager provide to divers?

• Ability to stay underwater indefinitely

• Ability to reach greater depths than before

• Ability to navigate without maps

• Ability to communicate with marine life

Which of the following is NOT a feature of the submarine salvager?

• Enhancing underwater speed

• Improving underwater communication

• Allowing for greater depth exploration

• Enabling work in stronger currents
