Canned Heat is a type of fuel made from a gel-like substance, often used for cooking or heating in portable stoves. It is commonly found in small cans and is popular for camping, picnics, and emergency situations due to its ease of use and long shelf life. The fuel burns cleanly and produces a steady flame, making it a convenient option for outdoor activities. The term "Canned Heat" is also associated with a blues and rock band formed in the 1960s, known for their energetic performances and hits like "On the Road Again." The band often incorporated elements of blues and rock and roll, and they played a significant role in the Woodstock Festival in 1969.
