Elephant’s Toothpaste!!!
Posted by Joshua Bartosiewicz- Woah, it’s actually working!
As the 8th grade continues to explore the realm of chemistry, we’re actively conducting experiments obtaining visuals of chemical reactions! Here, we conducted an experiment known as, “Elephant’s Toothpaste”. To execute this experiment we used the following materials; an erlenmeyer flask, a tin tray, dish soap, potassium iodide, 12% hydrogen peroxide and food coloring. We mixed 2TBS of potassium iodide with 30ml of water, meanwhile 100ml of 12% hydrogen peroxide was added to the flask. Once the peroxide was added to the flask, students added some dish soap and food coloring. Next the fun part, students added the 30ml of dissolved potassium iodide to the flask which would trigger a chemical reaction. The potassium iodide reacts with the 12% hydrogen peroxide and begins to release oxygen gas bubbles. Normally the bubbles would pop but the dish soap keeps the oxygen bubbles from dispersing, therefore foaming up and creating this “paste” like substance!
