Recently, I went to Guwahati to appear for an exam.
On my voyage, I came in contact with personal sellers of a certain type of repellant. She was neatly, officially dressed up, grin across her face, quite inspirational at the first look. She approached me and asked for a few minutes of my time. I was awaiting the due Network night-super schedule, so I agreed.
The next few minutes she took up all the efforts of explaining to me about the ‘mosquito repellent’ product she was selling. From our conversation, I came to know that she was not from the technical background, so she couldn’t explain about the internal principles of generation of the special ultrasonic wave which keeps the mosquitoes at bay.
I decided to carry the research myself and what I found out is a real simple laboratory principle…a basic electronics application. To know more about the working of these simple selling devices, download the pdf attached to this document. So that the next time you meet them, you should be explaining to them what they fail to explain to you.
