Eksperimen di Makmal

 Situasi di sebuah makmal di sekolah XXX

A student comes into his lab class right at the end of the hour. Fearing he'll get an "F", he asks a fellow student what she's been doing.
"We've been observing water under the microscope. We're suppose to write up what we see."
The page of her notebook is filled with little figures resembling circles and ellipses with hair on them.
The panic-stricken student hears the bell go off, opens his notebook and writes, "During this laboratory, I examined water under the microscope and I saw twice as many H's as O's.

Chi Alchemist : Formula kimia untuk air adalah H20.Bermaksud 1 molekul air terdiri daripada nisbah 2 atom hidrogen (H) dan 1 atom oksigen (O). Dalam satu titisan air, berkemungkinan terdapat berbillion-billion molekul air (automatik bilangan H dan O juga super super banyak....) Dalam situasi di atas, nampak sangat student ni menipu..hehe..sebab..adalah mustahil untuk melihat hatta molekul air H20,atom H,atom O menerusi mikroskop berkuasa rendah di makmal sains sekolah.
