Eating most candy is n’t complicated : You take a snack , enjoy a sugar - fueled dopamine rush , and repeat until you have a tum ache . ChemistWilliam A. Mitchelladded another step to the process when he germinate Pop Rocks . When the sweetened , hard candy bits hit your back talk , they act up before breaking down , creating a crackling , hissing noise that would be alarming make out from any other food ware . But when it happen to Pop Rocks , you know you ’re fuck off what you pay for . So what exactly is it about the candy that makes it just as much of a skill experiment as a sweet snack ?
The answer lies incarbon dioxide . It ’s the same gas that give cola , beer , and champagne their bubbliness , but it ’s not a rough-cut ingredient in solid intellectual nourishment . In the late 1950s , Mitchell wondered if it was possible to make an exigent soda pad by baking CO2into candy . Even though his idea did n’t take off , the experiments laid the basis for Pop Rocks .
Like other difficult confect , Pop Rocks are made by mixing refined sugar , milk sugar , corn sirup , and flavorings . Once those factor are melted together and boiled , extremely - pressurized CO2is summate . When the candy mixture hardens , it traps house of cards of gas exerting pressure at 600 pounds per straight inch ( psi ) . For reference , the imperativeness inside a champagne bottle quantity in at90 psi .

It ’s inconceivable to detect the special constituent in Pop Rocks unless you smack them . wizard things go on when the candy meets up with your mouth : As your spit dissolves the sugar , those powerful air pockets get down to explode like miniature firecrackers on your tongue . The 600 pounds per square inch carbon dioxide collides with the15 psipressure of the atmosphere , resulting in a crack you’re able to find and learn . That ’s why Pop Rocks areso noisy , whether you ’re eating them or standing next to someone who is .
And if you ’re distressed that all that pressure will do some serious equipment casualty to your body , you may rest soft . wayward to the hysteria from kid and parents , there ’s never been a known case ofdeathby Pop Rocks . That includes when it ’s assorted with Coke ( sorryMikey truthers ) .
