Hmm, all of the puzzles on here were fairly easy, the last was only difficult because i never "tried" my original idea, which turned out to be the correct answer ^_^;;;; But the REALLY weird thing is that this solution doesn't have a 100% success rate. (being if our computer lags enough to let 3, instead of 2 puffs hit the steam detector then it ends up killing to power receiver)
