Judas's belt

[2] the firecracker's name originates from its use in an old Catholic tradition during Holy Week in Spain and its former colonies, wherein a chain of firecrackers is strapped to a papier mache effigy of Judas Iscariot and then lit up.

The firecracker consists of a number of small explosives that can be either tubular or triangular in shape, wrapped in thick paper, and arranged sequentially along with a common fuse and a bigger firecracker at the other end.

[1] The small triangular shaped explosives, which is also known as triangulos, each measure typically 3⁄4 inch (19 mm) length in its longest side while the tubular shaped firecrackers, which is known as el diablos or diablos, each measure typically 1+1⁄4 inches (32 mm) long and 1⁄4 inch (6.4 mm) in diameter.

Its longer counterpart is called sawa, the Tagalog term for python.

[2][5] In the Philippines, Republic Act 7183 was enacted to regulate and to control the sale, distribution, manufacture and use of firecrackers for public safety.
