and then we had some hands on.
this is known as polygel, which can be found in diapers. when you add water the polygel will absorb the moisture from the water and solidfy. so after this experiment my hands still a bit itchy so i added copper (II) sulphate to have this very nice color. haha.
and this effect is called chemiluminence! it is formed by adding two organic solvents. the two organic solvents are dilute hydrogen peroxide in phthalic ester solvent, and phenyl oxalate ester in 1,2-diphenyl anthracene.
after lessons i went to meet leow chee leong and mak hong sen. they are giving me a belated birthday dinner treat. we ate at rama thai seafood restaurant. THE SHARK FIN ROCKS BIG TIME. no need to put vinegar and pepper but still taste very very nice.
and the whole meal is very ex. 60 bucks per pax. haha. cos the whole set meal is for 4 pple, and they dun have set meal for 3, so we bo bian have to order that. wah biang eat until damn full. i cant finish the fried rice and the dessert.
thank you mr leow and mr mak for the treat! and also the calvin klein perfume! :)
