Green Colour Flame...

It was during Chem Prac also...


B4 we almost finish our prac lesson,
one group of my frnz behind my group started to do some EXTRA experiment...


So, one of them jz mixup all the remaining solution into a boiling tube(contain a lot of ion like Cu2+, Pb2+, Fe2+, Fe3+, Mg2+, Mn2+, Cr3+ and ect ect...),
then they dipped a mechanical pencil lead into it,
and burnt it on bunsen burner...





Nice green colour flame... Wow...





They manage to capture a video 4 it also...






While they try to repeat it again,
suddenly our lecturer realised and came to have a look... (=_=!!)


She was veli veli angry and scold them... She also warning us that do not try to DIY any experiment without her instruction and permission as that will not only endanger ourself, but also may endanger other ppl life...


Yea, I can understand y lecturer is so angry wit that...


But, isn't tat last time many great scientist also doing a lot of crazy and dangerous experiment and tat lead them to discover a lot of useful scientific theory?? So, y us can't? Lol...
