You can send more than oil down a pipeline. Enterprising smugglers built and operated a vodka pipeline across the border of two central Asian nations:
It's believed to have carried mostly vodka through an 8 inch-wide tube over a third of a mile under the Chu River, which divides the two countries. The pipeline ended in the city of Tokmok in northern Kyrgyzstan.
Kyrgyz border guards found the pipeline during a routine search.
"We assume that thousands of liters of alcohol were smuggled," a Tokmok police official told AKIpress.
Government officials shut down the pipeline.
