I have bought a shocking gum which gives a small electric shock when you pull a side, like this one : http://img.weiku.com/waterpicture/2011/10/31/20/Shock_Chewing_Gum_634577515693532881_3.jpg
I wanted to know how it works so i opened it and there are two components i can't identify.

It's the black component (maybe a capacitor ?) and the little circular one I can't identiy. Any ideas ?
