Sutli bomb Wikipedia
Sutli bomb is made with jute twine (sutli) that is green in color and has a red band that has manufacturer's name. The twine is wrapped around the explosive component and results in producing a powerful sound.
It is banned by many governments under Arms Act, because of the noise level it produces that is almost double the permissible level of 75 decibels.
