ashbuster Posted March 2, 2012 Share Posted March 2, 2012 could be fake and not a real glass window? Link to comment Share on other sites More sharing options...
sideexitsupra Posted March 2, 2012 Share Posted March 2, 2012 I am guessing but, he starts in the middle of the window and increases the frequency of the tapping as he moves to the corner. Maybe this is setting up a resonance in the glass panel and when it hits the right frequency the glass breaks? All to do with harmonics. Not sure if you have ever seen the videos of suspension bridges swinging in the wind and then falling apart? similar thing i guess? http://www.youtube.com/watch?v=P0Fi1VcbpAI Link to comment Share on other sites More sharing options...
mellonman Posted March 2, 2012 Author Share Posted March 2, 2012 Why did you throw a brick at a car window? was a dumped car over some marsh/ creek land when i was about 13, thinking about it now i cant even answer why we wanted to smash the window young with nothing to do i guess Link to comment Share on other sites More sharing options...

ashbuster Posted March 2, 2012 Share Posted March 2, 2012 isnt it that stuff they make glass bottles from for in films? that break easier? hard to tell in the video but doesnt look like a normal window doesnt look thick Link to comment Share on other sites More sharing options...
AndrewOW Posted March 2, 2012 Share Posted March 2, 2012 isnt it that stuff they make glass bottles from for in films? that break easier? hard to tell in the video but doesnt look like a normal window doesnt look thick Sugar glass? Possibly, but I think that the vehicle glass was stronger than that, as sugar glass is very brittle. Link to comment Share on other sites More sharing options...
tbourner Posted March 2, 2012 Share Posted March 2, 2012 Anyone know what this thing is on his glove? And the fact he's leaning on the car at the start, then you see this hole just after it smashes: Link to comment Share on other sites More sharing options...

C_Strike Posted March 3, 2012 Share Posted March 3, 2012 The thing about resonant frequencies is that it is counter productive to change the Hertz (pace). Its more about maintaining the same, specific frequency as the natural bounce of the glass and only increasing the amount of pressure of each beat if needed without altering pace. I dont think its resonance as it is likely to be very hard to maintain the hertz precisely and you can see the guy tapping at different speeds as well as pressures and location. Fascinating video if it is true, but im guessing its manipulated in some way, IE: weak glass or something. Maybe he stole chuck norris' finger?

bradleyh_15 Posted March 3, 2012 Share Posted March 3, 2012 As a fireman I know plenty of tricks to break glass and get into a car quickly!! I would tell you but due to fire fighter code I would have to kill you lmfao Link to comment Share on other sites More sharing options...
mellonman Posted March 3, 2012 Author Share Posted March 3, 2012 well it works i went out last night to test it, its really quiet as well i couldnt belive it worked as scott said it wouldnt i havent run so fast in years Link to comment Share on other sites More sharing options...
Benjy Posted March 3, 2012 Share Posted March 3, 2012 Didn't you see my post? The guys got a punch on his glove, he was leaning on the car and flicked the top left of the window Could be something along the lines of an automatic centre punch. Or ceramic, depending how hard he flicked it. The ceramic from a spark plug will shatter a window nicely. I tried to break a window once. Full force hard as I could punch, 18 stone bodybuilder at the time, and a broke a knuckle! And the window survived! Got to be some sort of trickery.
