Bamboo torture is one of the most horrifying things you'll read about today.

Bamboo torture was allegedly used in East and South Asia. The torture consists of a bamboo shoot growing through the victim's body.

Japanese soldiers are said to have used the torture during World War II. How does bamboo torture work?

Well, bamboo shoots grow rapidly, are strong, and are sharp. The victim is tied to the ground or suspended over baby bamboo shoots and within days are impaled by the bamboo.

In 2008 Mythbusters did an experiment on bamboo torture and found that bamboo grew through several inches of ballistics gel within three days! Who thinks of these things?
