Bill Nye

Take a sip
change the shape of it
step on a fluid
and through it you will slip

If you're a liquid or a gas (you're a fluid)
if your shape will not last (you're a fluid)
If you're the air we breathe (then you're a fluid)

Now fluids,
Can change shape
Flow around
And circulate
Take a liquid
Or a gas
And you will know
What you have
A fluid
Fluid's good!

If the container is round (so's the fluid)
the air moves all around ('cause it's a fluid)
the water's pouring down ('cause it's a fluid)
We need fluids
Fluid's good!

I like fluids
Fluid's good!
