Exploding Jaw Breakers   (+9)  [vote for, against]
Well, bursting enthusiastically anyway.

Marketers have long added air and water to products for many decades. It is very cheap to do, adds bulk and if you can convince the consumer it is an 'improvement' then you're golden. Think of Aero Chocolate bars, Ivory Soap - "so pure it floats", extra cushiony toilet paper and so on.

My product consists of a high density sugar compressed into the shape of a standard jawbreaker/gobstopper with a hollow centre. Into this centre is a dollop of liquid flavouring and a quantity of high pressure air. When the victim, I mean 'consumer' dissolves enough of the outer coating they are treated to a high pressure blast of liquid flavour and sugary shrapnel shooting forth in random directions.

What's not to love? - dinner and a show for only a few cents.

The molten mixture is then exposed to high-pressure carbon dioxide. The pressure is almost 40 times more than atmospheric pressure of 600 psi. The carbon dioxide dissolves the sugar and the mixture is then cooled and the pressure is brought down. At this point the dissolved carbon dioxide tries to escape and in an attempt forms bubbles. But since the sugar is solidifying, large bubbles break the sugar into small lumps or rocks. [2 fries shy of a happy meal, Jan 12 2014]

Well, selling air is cheap, but can we say the same of selling p.s.i.?

Come to think of it, I believe "Pascal's" is a brand of confectionery in some places. No, wait - it's "Pascall". That's close enough.

CO2 is a liquid at 60 atmospheres. Just sayin'.

There was a brand of candy popular with grade school children and financially-minded dentists in the mid-late 80s that had a hard candy shell and the center filled with a tart, tangy substance that would foam up rather vigorously upon contact with saliva. Fun stuff. Can't remember what it was called.

sugar lacks sufficient structural integrity.

Lots of candy out there, but Fizz is the name of one like you describe. It's sold in segmented ribbons of plastic packaging.

Aye, that be the candy alright.

Gives me an idea for a weapon that when thrown in the eye fizzes as more tears are released from the stinging acidity.

Fizz=Yum. Bigtime

//sugar lacks sufficient structural integrity.//

Depends upon the thickness of the shell and the psi I suppose. I was a bit worried about the permeability but think that would be ok with sufficient density.

So, one big Pop- rock? [link]

That's gotta hoit.

Strontium would add fizz

With this, I could stop chewing on paintballs! I wouldn't -- but I could.
