I was thinking about visibility in general and then out of nowhere came the idea of an "invisbility bubble". Clearly this is something an inventor ought to sink his teeth into. But... to mix it up a bit I have let the Professor be much younger when this episode takes place. And it rhymes too!


Young Al was a curious boy That found all his pleasures and joyIn making up crazy inventionsDefying all normal conventions
Some were spectacular, shinyOthers were small, often tinyBut one caused him no end of troubleThe invisibility bubble
It was an amazing machineThe like of it hasn’t been seenNot even a closer inspectionRevealed a single reflection
The bubble was cosy insideWhich made it a good place to hideAway from the world for his schemingQuite simply a great place for dreaming
It happened in less than a blinkThat left him with no chance to thinkThat possibly, rather than cheering He should have equipped it with steering
The moment it started to rollThere was no way to regain controlThere seemed to be no way of stoppingIt simply was not keen on popping
The boy and his wonderous ballWent crashing right into a wallWhen it came it was quite a surpriseThe end of this brilliant device
