Me: "Hey Dragon! it's late afternoon what are you innovating there there so long...is something special delicacy is to be prepared?"
Dragon: "Yes! delicacies are being prepared, but hey I am getting difficulties with my kitchen appliances that keep on failing all the time."
Me: "They must be scared of you lolz, why what's up?"
Dragon: "See this time my gas lighter has failed, I wonder why... perhaps it's battery has gone out"
Me: "Lemme look at the lighter you've got... Lol your lighter don't need batteries, Now can you tell me how electric sparks are generated even if there is no batteries there"
Dragon: "Because I am standing near it!! DUH"
Just look at her simplicity, she thinks it works because she is near, may be she thinks there's some hmmm factor.
Then, I tried to explain her the Kitchen Physics about the lighter
Me: "See Dragon, many of us don't know that the electric sparks made by portable gas lighters are not driven by batteries. A peculiar principle of physics is associated with it, it is known as "piezoelectric property". What happens is, by the virtue of piezoelectric property some crystals like quartz tend to develop a voltage across it when it is deformed by mechanical pressure. Now such voltages can really be very high like in the order of thousands of volts. In the piezoelectric-ignition lighters a spring hammer is used to strike a quartz crystal which results in a sudden deformation of the crystal followed by a voltage of several thousand volts, this is then led to the spark knobs by connecting wires and we get sparks.
Look at its internal construction to know it better"
Dragon :"I've understood a lot"
