Almost all of us have the childish desire hidden deep within to blow something up. Whether we've experienced it with fireworks or made our own homemade concoctions, there has always been that pull. Now there is a way to blow something up right from your iPhone or iPod Touch. Sonic Boom presents a digital explosive that can be resized and customized before being blown to a million pieces. The app gives users the opportunity to light their finger on fire, tapp the fuse and count down until the explosive is destroyed. If this sounds like the biggest thrill in the world to you, you obviously have some issues.
