is a flashlight like.. a torch?

I assume that's wt the flashlight is for?

wowa all i gots to say and aryia i love you!

Oh i remember the answer..

Turn on Switch A, wait 5-10 minutes...
Turn off switch A

Turn on Switch B straight after, go up the stairs...

If the room is dark, the we know Switch B isnt the light switch..

feel the light globe with ur hands, if its warm, Switch A is the light switch.. if its cold then Switch C is the light switch.

You just said we have to determine which one is the light switch, but we don't have to arrive at the top of the stairs with the lights on right?

wow, you have done it before I see

Answer HOO!

I vaguely remembered something about warmth from the light globe...

i sat there and thought about it for 10 mins LOL!

AH, next-o teaaser! OKAY!!!
