How do you make a pressurized 2 litre coke bottle instrument Answered
I have found this video on youtube of this guy who made an instrument out of 2 litre soda bottles. He says he drilled a hole in the cap and put a tire valve through the hole. Then he used silicone to seal the hole, screwed in onto the bottle, and pressurized it. Then he hit it on his hand and other various objects and it produced a very clear sound.
I have tries to recreate this, pumping my bottle up to 120 PSI with no results. I noticed that he is from the UK and that his bottles were shaped differently than mine(from America), being more of an hourglass shape. Would this have any affect? Also i noticed that when i was doing it that there was a lower PSI(somewhere less than 100... mabye 80ish?) where i could hear a faint sound similar to in the video. Is it possible that I missed the correct PSI?
