There used to be a show on channel 2 that was very interesting. I am trying to remember the name of it.
It had two british guys that used to play around with various gadgets. I recall on one of the shows they explained how fuel injectors work. They rigged up a few injectors to squirt petrol straight into a candle, one by one.
On another episode, they took apart a VCR and showed the audience how it works.
It was a light hearted show. Similar in a sense to Mythbusters. I think it may have been a BBC production. Not sure. Does anyone know the name of it?
