Verse 1:

Look at the duck, floating so high!

Light as air, reaching the sky!

It has air, it’s not too dense,

Floating up, it makes no sense? (Oh yes, it does!)

Chorus:

Float or sink, what do you think?

Is it heavy, is it light?

Float or sink, what do you see?

Test it now, just like me!

Verse 2:

Look at the stone, heavy and round!

Drops so fast, straight to the ground!

No air inside, it weighs a lot,

Sinking down into the spot!

Chorus:

Float or sink, what do you think?

Is it heavy, is it light?

Float or sink, what do you see?

Test it now, just like me!

Bridge:

A feather is light, it floats so free!

A metal key sinks, just like you see!

A balloon has air, it floats so high!

A big rock sinks, oh my, oh my!
