Using an empty beverage bottle with a twist top, a drip button and a punch tool, you can make cheap irrigation bottles for potted or hanging plants. Similar set ups cost about $10 retail, so aside from recycling, you're saving money too! I had drip buttons left over from a previous project, but new they are less than a dollar. The tool was about $2.

Finish off a tasty beverage with a twist top. Cut off the label.
