Next, we dipped the leaves into alcohol (yikes.. I thought alcohol is not for under 18) ... Now,now don't worry, here alcohol is used to sterilise the leaves.. Then, the leaves are dipped into a bleaching agent.. Mmm.. but wat abt the hands and watches..What are they for? Well, we had Jymie and Swee Guan to help keep time.. otherwise, the leaves will 'die' for over sterilisation. We left the leaves in alcohol for 1 minute and in the bleach for 8 minutes.. (this process is called surface sterilisation..)
