How To Make Pumpkins Ooze #HalloweenScience #Chemistry Hydrogen peroxide is commonly used as a wound cleaner due to its ability to release oxygen when it breaks down, killing bacteria in the process. The same decomposition reaction makes it a fun chemical for foaming a pumpkin. When mixed with a catalyst like yeast or potassium iodide, hydrogen peroxide rapidly breaks down into water and oxygen gas. The oxygen gas gets trapped in soap, creating an expanding foam that spills out of the pumpkin—ju

Using Chemistry to Increase the Glow? #Chemiluminescence #Chemistry #HalloweenScience Dish soap can increase the glow of a glow stick by reducing the surface tension of the liquids involved in the chemical reaction. When added, dish soap allows the reactants to mix more efficiently by breaking down any barriers between the hydrogen peroxide and the phenyl oxalate ester, facilitating a faster reaction. This leads to a more intense but shorter-lived glow because the reaction releases more energy i
