caustic soda

[Dafni]

I don't really know about you guys in the states, but I'm sure you can get it at a pharmacy or however you call it. Actually hobby shops (or tool shops) may have got it too.

Caustic soda, aka Sodium Hydroxide (NaOH) is a solid. A powder or pellets. It's corrosive, and watersolube. Be carefull when you handle it. It burns your skin and would be very bad to have it in the eyes!! Wear gloves and eye protection.
