Hi.
The other day someone showed me a practical joke that gave me a 
painful electric shock. It looked like a book but when you 
opened the cover, SHOCK! It was powered by a 9 volt battery.
Do you have any idea how this thing works? How could such a big 
shock come out of a battery? Is it something I could make in a 
science project?
Thanks!
