They're called 'Drano Bombs,' or 'Bottle Bombs,' and they've been found on the lawns of a couple of homes in Hudson, New Hampshire.

Hudson police officers were recently called to an area near Barbara Lane to check on a report of two "Drano Bombs" or "Bottle Bombs.' A report from WMUR says the bottles contain drain cleaner and aluminum, which cause a chemical reaction that could cause the bottles to expand and explode. As you can imagine, these are potentially dangerous containers.
