Puking Pumpkin Science
What you get
Add a dash of spooky science to your Halloween decor — with an eerie, oozy chemical concoction you whip up yourself! Put your measuring and color-mixing skills to the test while blending together baking soda, foaming gel, and liquid colors. Pour the mixture into a carved pumpkin from home, add water and citric acid, then sit back as the chemicals react and make your pumpkin “puke”! Barf has never before been such a blast.

Would enjoy MORE explanation behind the science of "chemical reaction" and what is happening for explaining to the kids. Did just fine, and they loved it, but would be helpful for less nerdy parents I suspect.
