Gravity… the force of attraction that pulls bodies towards the center of the Earth
"Hold on to something or you’ll fall!"

Weight… the force exerted on objects in a gravitational field
"Don’t carry the weight of the world on your shoulders; it’s a heavy burden"

Heavy… Someone or something of great weight; hard to carry
"Never walk away with a heavy heart; you’ll regret it"

Light: Someone or something of not great weight; easy to lift
"Find the way to feel light as a feather. Fly!"

How can an object become lighter?By increasing the density of the air. Just like a balloon!
"He nearly blew her mind away. He drove her crazy!"

What if the air escapes?
The balloon deflates, loses its volume. It slowly falls
"There’s little you can do when the enthusiasm deflates…"

How do things fly?
When the law of gravity is broken. Like birds!
"Love gives you wings to fly, didn’t you know?

When do objects float?"
When they are lighter than the wind. Just like a balloon filled with hellion. 
Just like lovers “float” on the moon...

Thoughts in black & white

-Eternal enemies/rivals
-Forever friends
-Two sides of the same coin
-Day and night
-Light and darkness-Good and evil
-Ultimate contrast
-Perfect match!
