For years and years, as far back as you can remember, you can recall the sounds of an engine.
I got asked the other day if I know what’s making that noise.
It was quite a weird question at first because we just take it as the sound and engine makes, but all sounds have a cause… So, what was making that noise?
Well, these dudes cut off the top of an engine block and replaced it with acrylic so you can see exactly where that noise is originating from.
It is fascinating!
