A ‘Cause we belong together A We make our bed together F#m In a chemistry set, yes E We make the best of our lives, yes A We make our plans together A We take a chance together F#m In a chemistry set, yes E We make the best of our lives, yes [Chorus] D Why plastic burn on the other cheek A Your lips hot so they could burn me Bm Like we poured metals in a wet sink G We're volatile, volatile D But we burn as bright as magnesium A So when I’m away and you feel glum Bm Remember love in test tube G It's worth the while, worth the while [Verse 2] A 'Cause we belong together A We make our bed together F#m In a chemistry set, yes E We make the best of our lives, yes A We slow it down on Sundays A Stay out of town on Sundays F#m In a chemistry set, yes E We make the best of our lives, yes [Chorus] D Why plastic burn on the other cheek A Your lips hot so they could burn me Bm Like we poured metals in a wet sink G We're volatile, volatile D But we burn as bright as magnesium A So when I’m away and you feel glum Bm Remember love in test tube G It's worth the while, worth the while [Bridge] A If I'm your acid, you're my alkali A We'll find the right P.H. to make things right F#m We'll settle differences to make it last E And place our worries firmly in the past A If I'm your acid, you're my alkali A We'll find the right P.H. to make things right F#m We'll settle differences to make it last E A And place our worries firmly in the past
