I spin but never travel, I hold the world but never leave my stand. What am I?

I have no hands yet I can hold I have no mouth yet I can drink I wait beside the water And take in more than you might think I become heavy when I am full Yet lighter when my burden leaves I hide countless little spaces Where drops of water choose to sleep I help to clean what others leave Then give it back when I am pressed I may be soft within your hands But after work I need my rest I can live beside the sink Or travel with the tide One of my kind cleans up your home Another lives beneath the wide What am I

I have no legs, yet I wander the sea, With wind in my sails, I roam wild and free. I’m dressed up in luxury, polished and bright, A floating palace by day or by night. I chase no treasure, yet riches I bear, I glide where the ocean meets open air. What am I?

On a door, I can glimmer And lock things up tight. You can try to pick me, But keep out of sight. Thieves despise me, While voyeurs delight- An eye made of metal, That goes clink in the night.

I am very good at keeping secrets, especially from people who forget their keys.
