Hello
when i saw "meet the fockers" it has enlightened me with this nasty chemical
Sodium pentathol or truth serium (watch it and see what happens)

How could u make pentathol? and whats the chemical formula of Sodium pentathol?

Sodium Pentothal (aka Sodium thiopental, thiopentone sodium, trapanal) is basically just a general, fast acting anesthetic.  The formula is C₁₁H₁₇N₂NaO₂S.

More often, it is given as an anesthetic before using other anesthetics.  It is also used in lethal injections.  Like you said, it can also be used as a truth serum.  It's actually quite interesting how it works.  It interferes with your judgement and cognative ability, making you an easy target for someone to get information from.
