How to explain?

Tweet

As I have said in my previous discussion on Rath Yatra or car festival, I am enjoying the live telecast of the festival at Puri in my state Orissa with my granddaughter Subhee and my 10 months young grandson Bishu, you can see him on his walker. She is holding the remote control of the TV and keeps changing channels because it is telecasted in several channels. I always say she is intelligent and a keen observer. The same scene seen and the voice of the commenter heard in different channels have little time delay; it is so because the data transmitted from the transmitter near the Chariots has to pass different distances in reaching the TV set; some may have to travel around the globe via the satellites. This Subhee could mark and asked me the reason. She is just 4 years young, I can’t convince her about satellites, signals etc; so; on paper I drew one globe, over it antennas and high above satellites, drew lines to show direct and around the globe signal reach; any way she is convinced; but not fully; she will ask me later; I have to quench her thirst for knowledge. [b]Can anyone suggest ways and means? How you explain your kids/grandkids? We must try to give correct information as far as possible.[/b] Please share and comment on this story.
