¹ Gravity affects all things
It moves things great and small
But mostly by attracting them
By gimbaling you recall

² But Einstein found a place
That works the other way
By its hidden repelling force
It changes what things weigh

³ The fields that interconnect round things
Like atoms and the like
Are called bonding shells
That really make things light.

⁴ It isn’t very strong you see
It’s not nuclear for strength
But it spreads its effect
Along thing’s entire length

⁵ The important thing that’s different
‘tween these and other fields
Is that they are no longer round
But fit the shape from where it yields

⁶ That gives us here a secret clue
To find out how we can
Make antigravity for real
A sure and vital plan

⁷ It tells us that the shape of things
Affects their gravity
And gives us that most secret clue
Why it’s attraction that we see

⁸ So all we have to do to make
A mass to fly about
Is turn its atoms upside down
While holding them real stout

⁹ You cannot let them gimbal
You mustn’t let them spin
With this new configuration
Then antigravity can begin.

Simple isn’t it!
