In the experimental process my tongue learned to tell positive from negative and voltage within 2 volts up to a painful 12VDC. Also DC and AC. BTW 52 ibles in just a little less then a year WOW A. I do this all the time to check 9V batteries. I don't see why some people think this is dangerous. I even had one guy warn me that I'm going to kill my self after he saw me do it once : 9V batteries can't put out all that much current, and the current that does come out just goes from one spot on your tongue to another spot less than an inch away.
Sure it might sting a little it more just tastes funny but it's nowhere near your heart or brain so you'll be just fine. Reply 9 years ago on Introduction. By amandaghassaei uh-man-duh-guss-eye-dot-com Follow. More by the author:.
The nine volt battery has six 1. You could make a 6 V or 9V battery as small as you like within reason. All alkaline batteries are 1. What does electricity taste like? When you lick a battery, your saliva causes the electrons from one end of the lead to start moving to the other, creating an electric current. The electrons also interact with water molecules in a process called electrolysis, which produces hydrogen and oxygen gases. Terms and Conditions Warranty.
When I put a 9v battery on my tongue why does it tingle? Home Blog When I put a 9v battery on my tongue why does it tingle? I don't know if that would make a difference, but it's what I was taught. I learnt the back of your hand trick in relation to watching something about how to escape from a building in a fire or other emergency, and is a useful one to pass on.
If you're, say, using your hand to find your way against a wall in a dark and smoke filled build, use the back of your hand so as not to accidentally grab onto any exposed wiring. It is very dangerous to touch any high-voltage wire. Never use the back, or front, of your hand to test for a live wire.
Instead of your body, use a multimeter and make sure it's rated for the type of voltages you're working with. Rules 1 , 2 , and 3 are really good though. Additional rule: Remind yourself of all of the above often. My father an electrician used to drill these into me as a kid, and got forgetful one day Tesla's rules!
Words to live by and die by ignoring. Though I'm having trouble finding any citation of them as Tesla's. And this is why a lot of digital EEs like me are afraid of high power stuff. The real fun starts above mA, where the danger of arrhythmia and nerve damage abate and you're simply cooking the tissue in situ.
Engineers plump when you cook 'em! At my high school, the electronics instructor assigned everyone the taks of making an electric hotdog cooker. One evening in college, I learned a lot about the way telephones work after some excitement I was relocating a telephone line in a room we were remodeling. I had a habit of stripping small wires with my front teeth. I had stripped one wire of the pair, and I stuck the second wire in my mouth to complete the pair. Apparently, the first wire I had stripped was laying against my nose when the phone rang I saw stars The story about licking 9v batteries reminds of a Jr.
High School science fair many years ago. He had problems getting it to work. The radio was powered by a 6 drycell for the filament, and a small "B" battery of 45 or Anyway nobody had a volt meter so the guy first tested the 6 dry cell with his tongue barely gave him a sour taste, but we figured at 1. You've probably guessed what happened next. Needless to say that B battery wasn't completly dead.
The galvanic reaction caused a muscle spasm that ended up with the battery being pitched out the window! Poor idiot had a splitting headache all afternoon! He was fine the next day BTW. I know nothing about electronics, I just read this article and registered so I can ask this question: When I was a small child there were unfinished renovations in our house and that involved some power points sitting out from the walls for months.
