Pulse Jets

The first pulse jet I ever saw was at a control line contest. It was INCREDIBLY LOUD and the guy nearly cork screwed himself into the ground flying it. As an 11 year old, I was impressed. Always wanted one to play with, but they haven't made Dyna-Jets in years. Found this out on the internet and thought others might enjoy also.

Read the article over at Hack A Day complete with video. I'm still impressed by the sound.
