Tirapó
A homemade noisemaker or toy popper. One version uses a hollow faucet piece filled with match head powder and a nail that strikes it to cause a small explosion when hit against the ground. Another version is a paper popper made from notebook paper that makes a loud snap when shaken or flicked. (Commonly crafted by children in Dominican neighborhoods using recycled materials).
The dog got scared when they set off the tirapó and it bolted.
