Brain Teasers
Lots of Volts
Mike was a very intelligent kid. He told his fifth grade science teacher that he knew how to create thousands of volts of electricity with only a comb. The teacher didn't believe him and told him to prove it to her. The next day Mike proved it and brought information on the subject.
How did Mike do it?

Answer
He brushed his hair with the comb. Brushing your hair with a comb separates the positive and negative charges in the comb and thousands of volts of static electricity can be measured.Hide Answer Show Answer

This one probably one of the easiest here
Not really... i never would've guessed it in a million years. Obviously, everyone knows it creates static.. but 1000's of volts?????????? I'm pretty sure you didn't know that... actually, I dont' know if i believe it lol.
Hahahahah, I knew there would be people that wouldn't believe it but that dosent make it wrong. This ones my first teaser .
I think you found a way to solve the worlds energies problems, we need to hook up wires to the comb, and comb away!
Good Teaser.
Good Teaser.
Ok, then send me a link to a credible site, and I'll believe you. Maybe.
that's funny but i have to say this was an easy one, but a good one for your first try!!!
This was kind of fun, but technically he didn't use only a comb. He was using the hair. If you are going by those rules, he could've let the comb get struck by lightning, or used a comb with a cord and plugged it in- just about anything.
Either of those would've resulted in him being quite dead...
After doing that to your comb, go to a sink. Turn the water on to a small thin stream. As you but the comb near it, the water will bend towards the comb. Cool trick, thank God for Mr. Wizard on TV when I was young. (I'm still young, we late twenty somethings will remember Mr. Wizard).
This was very easy but there is no way a comb and hair can create enough energy to power a house.
damn right.
pretty cool for a first try. i feel proud this was one of the few i got, keep up the good work. but seriosly wouldnt it be cool if we didint have the electricity bills, cuz we oculd mke our own... maybe it is farfetched?
Y\'all need to be aware that amperage has a whole lot to do with electricy. Its the workhorse of an elctrical current. Static electricity with thousand of volts has a miniscule amount of amerage (ie. 0.01) A 9 volt battery with enough amperage could buzz your arss!
threw it up in the air and it got struck by lightning used nutin but luck you fell it slipped in a criminals pocket then he sat on the electric chair random it could be lots of things my personal favorite is that he falls, the comb is stays int he same place for ten years and some stupid kid decides to fling it at a power line and split it apart causing enough power to power someones house for a long time if it doesnt burn down
Didn't know it was so many volts, but good teaser.
Pretty easy, but we just studied electricity, nice try
I'm an early twentsomething and remember Mr. wizard.
'twas easy as pi. HAHA like my mathmatical plug? Wow, i am a dork...
It was easy...but good! I dont claim to understand how static electricity works, But I did see it on myth busters, so I know that it is correct. Static can set off the fumes when you're pumping gas.
It's caused by the friction made when your clothing rubs against the cloth seat. Dont forget to discharge by touching metal!!!!

STATIC ELECTRICITY" is not unmoving, it really means "HIGH VOLTAGE ELECTRICITY."
When you scuff your shoes upon a rug on a dry winter day, your body typically charges up to a potential of several thousand volts with respect to ground. In physics this is a well-known fact and is easily verified by meter measurements

Thanks for the comments. I love electrostatics
I knew that people woldnt rate the teaser well because they dont't "believe" the science behind it. It HAS been proved.
Here is a very nice page about the subject:

well i believed it. after all, even some vegetables can power a lightbulb for a while, why not carge up thousands of volts with a comb?? good one.
Good one- I always like it when the balloon sticks to your head!!!
Actually, static does mean not moving. It's not high voltage, it's low current. Amperage is far more important.
I knew that!
(but it's low current)

What a dumb teacher.
On the subject of static electricity in general:
Static electricity is a bit of a misnomer. Static means unmoving. Electricity is the FLOW of electrons. So "static electricity" is an oxymoron. The proper term for the electrons that accumulate on a comb, or anywhere else, is "static charge."
The spark you sometimes see when you touch a metal object after walking across carpet is the dissipation of static charge. The spark you see is no longer static, but rather high voltage dynamic electricity bridging the gap between your body and the grounded object.

he's using his hair so e is using more than a comb
this question is a little 2 easy...but it is still very fun to see this type of question!!!
