Right clicking a tiny(size 1) slime with a bucket puts it in there.                                                     
It remains quiet, but will start jumping inside the bucket if you find yourself in a slime chunk.
The slime can also be deployed back into the world by right clicking on a block.

A Trowel tool can be crafted with Iron and Sticks. The
Trowel, when right clicked, will place a random block from your hotbar, making it useful for ruins or paths.

Using a Glass Bottle at the cloud levels (126-132 by default) will get you a Bottled Cloud.
The Bottled Cloud can be right clicked to produce a block floating in midair in front of you. The cloud block disappears after a few seconds, but you can right click it with any other block to replace the two.
