can electronic penetrate the glass?thanks
Glass is an insulator.
Sometimes. My "beer-bottle" capacitors which are filled with, and surrounded by, salt water, occasionally give up under the stress of 20,000 volts (Tesla Coil, wouldn't you know?). jocular
Thanks for your reply,I ask because somehow learned a saying goes like this"watching TV for so long can do harm to you because it generated electronic and brought it into your eyes and face".Now i understand. ----L.spark
Seriously- I wanna hang out with you one weekend...
Ok, this is an entirely different question than the O.P.
It refers to an E.M. Field, which some people believe (As in, have faith in without strong evidence) that E.M. Fields are harmful.
I would say that watching too much television is bad for you, not because of the electronics, but because it promotes a sedentary lifestyle.
While the E.M. field moves around you, you're more likely to have a heart attack from a cheeto's snack lodged in your aorta.
Electrons don't penetrate glass, but x-rays do. A cathode ray tube, such as the one in older televisions and computer monitors emit a small amount of x-rays but not enough to worry about. The newer style televisions with plasma or LCD screens do not emit x-rays. Any kind of electronic device will give off electromagnetic radiation, similar to radio waves, but it is not ionizing radiation. Ionizing radiation like x-rays can cause cell mutations which could cause cancer.Why should we sit far from the TV? - The Naked Scientists
Above and beyond the commonplace has always lured me seductively! 8th. Grade, blasting powder (accident, 2nd. degree burns), then high-voltage experimentation, first Tesla Coil built for high school science fair, then learned dynamite was buyable by anyone (this was LONG ago!), then a big Tesla Coil, built as part of a Special Credit I offered the Seniors while teaching High School Math. Intermingled amongst those exploits were many experiences with all kinds of firearms, including a Civil War cannon.
Still interested?

Yeah,I told my mom many times stop watching South Korean TV soaps for this reason,however,you know the result...
Neither, actually. I enjoy target shooting, the psychological reward of being able to train one's self to attain proficiency in markmanship. I do not hunt, as I believe killing for "sport" makes no sense. Regarding the cannon, I accepted the request of a young man co-student of mine in college, that I store it temporarily in the basement of my parents' house (I still lived at home). It was a steel casting, muzzle loader, 3-inch bore, rifled, about 8-1/2 inches in diameter at it's closed end, had trunnions on either side for mounting, dated 1862 on the muzzle end. I turned several wooden projectiles on my lathe, and we fired them the length of the basement against the far brick wall, using a very tiny amount of black powder. It was quite a rush!
Allan decided to move it after several months, my parents having been most graciously understanding of this latest bit of madness exhibited by their son, and it was hauled away, open and in public view on a flat bed trailer, supported by the pedestal I had built, on Independence Day, July 4, 1962! He passed several police cars enroute, but drew scant interest, due to the choice of moving day!
Too crazy to have been a made-up story, no? jocular
Agreed.
Now see... This is where we are different people.
I would have left the cannon mounted to the truck in order to deal with people cutting me off or passing on the right (Left for you British folks).
Or perhaps, used it for highway privateering...
"Hard to Port, scurvy dogs! She'll be pullin' alongside; prepare the cannon! Pedal to the metal, me mateys; we'll blow 'er doors off and make hey with th' booty!"
