Connection

"From little spark may burst a mighty flame."

~ Dante ("Dante Alighieri") , Source: Paradise (canto I, l. 34)

 

When the right connection is made, sparks fly. That is certainly true when you connect the terminals on top of a 9 volt battery with steel wool fibres.

 

To see what happens when you hold the connection too long, see my other pic: flic.kr/p/Y6Wn8b
