In that case I don't know about it.. Its just like Sandhaya mentioned, only few paper remains after it... Let me see if there is any chemical on next diwali.. ha ha

Sasi...if it is burned then you can't use it. If it is not burned with the explosion then only you can use it. :)

Meera sandhu
Ok sandhya I agree with your opinions but I had done experiments also.
