All Rights Reserved.Website by Parkway Digital, Pre-purchased tickets required. American Chemical Society, Reactions ‘Elephant’s toothpaste’ reaction explained in slow motion.

To create the elephants toothpaste reaction a second chemical is added (know as a catalyst) which basically tears-apart the hydrogen peroxide into water while releasing Oxygen gas inside the bubbles. In the end, of course, this video was much more than a large scale science experiment, it was a chance to celebrate a strong and brave young man, as well as embrace the good and joy that comes when people collaborate and work hard to create something special for others. Stir for about 15-30 seconds.

FREE for Museum Members and children under 2. Watch the full video here: So much testing…. The added reaction also came with added danger and we were constantly reminded just how much we need to respect the power of chemistry which is why we’re not sharing it publicly just yet. Hydrogen peroxide is basically water (H2O) with and extra oxygen (making it H2O2 ) But don’t be fooled into thinking it is close to water. Here the neck size caused the foam to go confetti.

Each attempt was tracked for every variable we could test and cataloged on an ever growing database. The higher percentage of hydrogen peroxide (H 2 O 2) used, the more energetic the reaction will be.I use 3% because it is cheap, available, slow, and safe.

The cobalt chloride speeds up the chemical reaction because it speeds up the decomposition of hydrogen peroxide to form oxygen gas.

So, as the oxygen molecules are formed by the reaction, the soap bubbles capture them and it creates a lot of foam! gtag('js', new Date()); Elephant's Toothpaste . The cylinder does become hot and is dangerous to hold. Purpose/Goal: Procedure presents an example of a catalyzed reaction. Hydrogen peroxide is used for many things—it is a common antiseptic and is in a lot of cleaners.

The cobalt chloride speeds up the chemical reaction because it speeds up the decomposition of hydrogen peroxide to form oxygen gas. A catalyst speeds up the reaction of an experiment. A catalyst (often potassium Iodide or yeast). Try the experiment without soap—how is it different?

Next up was the 5 foot version. I'm using hydrogen peroxide, like you might use at home, except this kind is much stronger. It’s chemical formula is H2O2, so every molecule has two hydrogen atoms and two oxygen atoms. The Devil’s Toothpaste demonstration was basically the elephant’s toothpaste demo on steroids. It looks like toothpaste, but it is not - it's a chemical reaction!Open Activity. Always wear plastic gloves when working with 30 % hydrogen peroxide. In this experiment, the yeast is the catalyst that breaks it down. This is the classic “Elephant Toothpaste” reaction. The point of this demo is to decompose the hydrogen peroxide (H2O2) as rapidly as possible, which generates gaseous oxygen (O2). Perhaps the only thing better than the classic elephant’s toothpaste experiment, is the elephant’s toothpaste experiment at an absolutely colossal scale! We knew we wanted the flow from the flask to be laminar, meaning it stays in a column of foam and does not break up into “confetti” when it leaves the flask – this was one of the biggest challenges from a chemistry stand point. 1020 Humboldt Parkway Buffalo, New York 14211, Before visiting, please review updates and policy changes in response to COVID-19, 3% hydrogen peroxide (Warning: keep this out of your eyes, as it is an irritant). Does it change the resulting reaction? Elephant Toothpaste Video.

That is why I'm wearing gloves and safety glasses. Concentrated hydrogen peroxide can result in a strong chemical burn if it gets on your skin.

Heat Up, Cool Down. It was all about pressure and flow to keep it laminar and keep the flask intact. Step 1 – Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water. After each test, Mark and the team would get on a call, review footage, and figure where to go next. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. The detergent captures the oxygen in bubbles, which is what we see as foam. 30% hydrogen peroxide is added to a glass cylinder containing a concentrated aqueous mixture of potassium iodide and dishwashing soap.
