But what about the candy coated popcorn and peanuts? Is there room in the box?
Or Pop Rocks candy.
(article excerpt)
There was an urban legend that Mikey, the kid from the Life cereal ads who won’t eat anything, ate Pop Rocks and washed them down with cola, and then died when his stomach exploded. It’s completely untrue. If you swallow a handful of Pop Rocks and chug a soda, you’ll probably burp, but you won’t die. If Mikey barely tried Life cereal, why would he eat Pop Rocks anyway? How exactly do Pop Rocks work?
How Pop Rocks Work
Pop Rocks are a hard candy that has been gasified with carbon dioxide using a patented process.
Pop Rocks are made by mixing sugar, lactose, corn syrup, water, and artificial colors/flavors. The solution is heated until the water boils off and combined with carbon dioxide gas at about 600 pounds per square inch (psi). When the pressure is released, the candy shatters into small pieces, each containing bubbles of pressurized gas. If you examine the candy with a magnifying glass, you can see the tiny bubbles of trapped carbon dioxide.
When you put Pop Rocks in your mouth, your saliva dissolves the candy, allowing the pressurized carbon dioxide to escape. It’s the popping of the pressurized bubbles that makes the sizzling sound and shoots pieces of candy around in your mouth.
