Hello. I had a little shock yesterday. Two actually. First is that one of my 1st year lecturer relief (I think this is how it is being spelled) my class since my original lecturer was busy with somethin (is it even possible to do that?) and the lecturer that took over ismy all time favourite! Mdm Lau!! A couple of my classmates were happy to see her too! Yea!! 2nd was durin the practical. Es was restin his hand on a metallic board that we "clip" or "click" some of the PLC apparatus onto and we switched on the power supply so that the whole mechanical stuff have current flowin through them. Neither do me, Es or Shah knew that who ever rest their arms or hand on the table will cause their whole body to be "live". In other words, current is passin through the person's body makin them feel static when comin into contact with anyone skin.
