Small and worn close to the heart, I open to reveal what you keep dear. A tiny place for memories or faces. What am I?

I glow without flame, die without air, and live in the hearth with a fading light. What am I?

A cozy boat where bubbles play, a watery bed at the end of day. In its quiet embrace, worries float away.

A pendulum pivoting around a single point, out on yonder playground as a popular pastime. Ah, how the youths propel themselves to such ponderously great heights.

For a massive sporting company, I describe the noise and motion their silent logo makes.
