The "tube within a tube" refers to the concept of a "concentric tube" or "concentric cylinders," where one cylindrical tube exists inside another. This structure is commonly seen in various applications, including engineering and biology, such as in blood vessels or the gastrointestinal tract. The design allows for efficient flow and insulation between the inner and outer tubes.
Rocket type fireworks have fast burning propellants in them that make them shoot up. Artillery shells have a casing of gunpowder at the bottom of them which pushes them into the air when launched out of a tube. Roman candles have gunpowder underneath each of the stars it contains which shoots them in whatever direction you point the tube.
The firework that consists of a tube sending out a shower of sparks and a succession of colored balls of fire is commonly called a "Roman candle."

The inside of a wave when surfing is commonly referred to as the "barrel" or "tube." This occurs when the wave curls over and creates a hollow space that surfers can ride through. Riding inside the barrel is considered one of the most exhilarating experiences in surfing. The term "tube" can also refer to the shape of the wave as it forms a cylindrical tunnel.
