Solid things seem solid, but
look closer and they're not. The particles inside are
moving, especially when it's hot. And as those babies start to
spin around with lots of vigor, They push themselves apart a
bit, which makes the stuff grow bigger. Chorus It's our
understanding Heat will cause
expanding. Some things grow
more. Some things grow
less. That's just the way it
grows.
