Buckets

A bucket is used to carry liquids (lava or water). Each bucket holds one full square/tile of liquid.

Click on any sufficent body of liquid with the Empty Bucket to collect the water into the bucket (water will make a Water Bucket, lava - Lava Bucket). Clicking again will deposit the liquid at the location of the mouse (this also works in mid-air).

It's also possible to wear an Empty Bucket as a helmet. It gives +1 defense.
