Cocaine submarine? Wouldn’t it dissolve in water?

First thought that I had when I saw the article; swear to God.

Officials seize cocaine submarine

Guatemalan and US authorities have seized a makeshift submarine loaded with cocaine with a US street value of $200m (£120m).

The submarine, which had 10 tonnes of cocaine on board, was arrested by the coast guard some 280km (175 miles) off Guatemala’s Pacific coast.

My second thought was that if I was smuggling 200 million dollars worth of anything I’d probably want to avoid using a transport device that could be described as ‘makeshift;’ but then, I’m not a smuggler.
