WARNING: turn your volume down before watching this video. And while you're at it, go read this post, paying close attention to the parts that address the pitfalls of liquid nitrogen bomb assembly.
Read the line about only setting off liquid nitrogen bombs when you have plenty of space at your disposal. Understand that you should use that space to keep yourself FAR AWAY FROM LIQUID NITROGEN BOMBS. Did you read it? Good.
Because this guy clearly didn't.
Remember: liquid nitrogen boils at temperatures far below room temperature. When it does, the volume it occupies expands by orders of magnitude. Translation? LN2 + sealed plastic bottle = kablamo. This kid got very, very lucky.
