my son would like to know if someone out there knows what it is that makes them pop and if it could be made at home. i'm guessing it's some kind of cardon dioxide thing going on but, i really have no idea. thanks for your help.

Here's a good page to look at--tells everything you need to know: http://science.howstuffworks.com/question114.htm
I think it's not very practical to make these at home because you need to use CO2 at 600psi with the molten sugar--not sure how easy that would be...but it's a cool idea!

They are so great!!
To make Pop Rocks, A hot sugar mixture is allowed to mix with carbon dioxide gas at about 600 pounds per square inch (psi). The carbon dioxide gas forms tiny, 600-psi bubbles in the candy. Once it cools, you release the pressure and the candy shatters, but the pieces still contain the high-pressure bubbles (look at a piece with a magnifying glass to see the bubbles).
When you put the candy in your mouth, it melts (just like hard candy) and releases the bubbles with a loud POP! What you are hearing and feeling is the 600-psi carbon dioxide gas being released from each bubble.
As far as creating some homemade version, I don't think you can...
