In this instructable I'll be showing you how to make an exploding doorbell made from common electronics parts you can get at your local radio shack and hardware store.
Step 1: Materials
*A Doorbell (duh)
*An SCR or Silicon-controlled rectifier (optional but highly recommended)
*A Soldering Iron
*one single SMALL, key word SMALL firecracker. (See picture for what I mean by small. there's only a handful of standard sizes for
firecrackers and the smallest pack more than enough punch.
*A small 1 cell LiPo battery( < 300 mah) these can be found in rc toys and can also be found sold separately at hobby shops
