Hi Thilo,
Kaboom!! No, don't want that to happen. Thanks for the advice. It's like you can tell I'm into experimenting things.

Actually these chemical stuff is pretty hard to get here in Malaysia. There's a nutcase around KL recently goes around splashing people with acid for no reason. He is still at large. So, at the present time, I think if I try to buy any acid without proper papers, I'm certain people would give me a frighten look and dial 911.
