You should be mindful not to hold on to the container where the reaction is taking place unless you're wearing gloves or another covering that will shield you from heat. Elephant Toothpaste Last updated; Save as PDF Page ID 128806; No headers. Want to master Microsoft Excel and take your work-from-home job prospects to the next level? You also wouldn't want to touch the foam afterward, because there may be un-reacted peroxide in it. 1 package of yeast vs 2 grams Potassium Iodide. It’s short, and clear and simple. 2. 94. First we pour in the hydrogen peroxide, then the soap and … Clear plastic tub. You will be testing how a catalyst affects a reaction. You should swish the ingredients around in the container to create a mixture. Every chemist wants to try this experiment, but which catalyst produce more of the foam? ScienceBob put some cheap, easy-to-follow instructions on his website, and the experiment is kid-friendly as long as you follow some basic safety precautions. FREE Shipping on orders over $25 shipped by Amazon. If you use dye, it can stain ceilings to the point where it's almost impossible to clean. The iodide ion catalyzes the decomposition of hydrogen peroxide, generating oxygen gas which causes the soap to foam up and shoot up out of the cylinder. Potassium iodide 2 M – Prepare stock solution by mixing 33.2 g KI in distilled water and dilute to 100 mL; Dishwashing liquid – approximately 5 mL; Food coloring; Graduated cylinders – 500 mL and 10 mL; Large serving tray and rubber gloves to assist in cleanup; Measure 20 mL of 30% hydrogen peroxide into the graduated cylinder. Jump-start your career with our Premium A-to-Z Microsoft Excel Training Bundle from the new Gadget Hacks Shop and get lifetime access to more than 40 hours of Basic to Advanced instruction on functions, formula, tools, and more. A Ukrainian YouTuber has created a crazy expanding "elephant toothpaste" experiment using different chemicals and household objects. You can do this as a school project or for fun. Given these safety precautions, its best to leave this one to the experts. Make sure the bottles are identical and that students understand both bottles … Footage from January 24 … Dr. Lithium from NurdRage has answers. Elephant toothpaste is the decomposition process of hydrogen peroxide, while yeast / potassium iodide works as a catalyst to break down the hydrogen peroxide into oxygen and water. loads of info on how to make this awesome foaminess!THIs is a really cool video, Premium A-to-Z Microsoft Excel Training Bundle, 97% off The Ultimate 2021 White Hat Hacker Certification Bundle, 98% off The 2021 Accounting Mastery Bootcamp Bundle, 99% off The 2021 All-in-One Data Scientist Mega Bundle, 59% off XSplit VCam: Lifetime Subscription (Windows), 98% off The 2021 Premium Learn To Code Certification Bundle, 62% off MindMaster Mind Mapping Software: Perpetual License, 41% off NetSpot Home Wi-Fi Analyzer: Lifetime Upgrades, What's New in iOS 14? Uhas told Insider that he tried the experiment inside Dobrik's house, and the stained ceiling now rejects new coats of paint because the iodide seeps through. Combined with 35% Hydrogen Peroxide though was the best … This does work, however when combined with 3% Hydrogen Peroxide, it is a terribly slow reaction. In this experiment, we received a so-called elephant toothpaste. Hydrogen peroxide (30% strength) will act as an oxidizing agent with practically any substance. Soap will then mixed with the oxygen and water, which turn into foam. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide This is often used for classroom demonstrations because it requires only a small number of ingredients and makes a "volcano of foam". A catalyst (often potassium Iodide or yeast) Soap; THE CHEMISTRY Hydrogen peroxide is basically water (H 2 O) with and extra oxygen (making it H 2 O 2) But don’t be fooled into thinking it is close to water. Fill the vial containing potassium iodide with water. The mixture will then produce a massive foam. If you use potassium iodide as the catalyst, Uhas told Insider that it becomes iodine, which leaves a powerful stain – another reason to do the elephant toothpaste experiment outside and away from your house or any sort of concrete or plaster. This large demonstration uses hydrogen peroxide (H 2 O 2), sodium iodide (NaI) and soap. This chemical is ideal for science experiments requiring potassium iodide crystals! A great fun demonstration of the action of a catalyst and also of an exothermic reaction. The main components are hydrogen peroxide 30%, potassium iodide and some dishwash liquid. Elephant’s Toothpaste This classic chemistry demonstration is a huge hit with kids of all ages. In all of these experiments, what's happening is the hydrogen peroxide is being catalytically decomposed into water and oxygen by the iodide or the yeast. The remaining liquid is also drain-safe. In this experiment the detergent captures the oxygen while releasing the heat, therefore making an explosion of foam like substance. Because it is often har… Performers Required: 1. I am looking for sodium iodide to make elephants toothpaste, will potassium iodide work the same? Because it requires only a small number of ingredients and makes a "volcano of foam", this is a popular … This Ukrainian YouTuber has staged a massive foam volcano eruption. Required PPE. You can also do the demonstration without dish soap, and the reaction will still take place, but it won't create the bubbly foam. The title becomes obvious as the reaction converts … What is Elephant Toothpaste? … Then potassium iodide is dropped in. More Buying Choices $17.94 (3 new offers) Elephant Toothpaste: Explore Catalysts, Chemical Reactions & Phase Changes - Chemistry Demonstration Distance … The elephant toothpaste is a dramatic chemical reaction which produces tremendous amounts of steaming foam that sort of looks like the toothpaste an elephant might use. First mix 50mL of detergent with 100mL of 30% hydrogen peroxide. 4.5 out of 5 stars 357. Yeast can be used in place of iodide for a slower reaction, but this also allows you to add fluorescent dye to the mixture to make a "glowing elephant toothpaste" when you shine ultraviolet light on it. Uhas told Insider that the iodide isn't toxic, and is actually edible, but it's used for medical purposes and is more expensive than yeast. Have you ever heard about a viral experiment called Elephant Toothpaste? A catalyst speeds up a … 2. Screenshot YouTube/Mark Rober (L), Nick Uhas (R). This translated to Uhas using 625 liters of hydrogen peroxide, which was 245 liters more than what was used for Rober’s elephant’s toothpaste; he also used potassium iodide… 1 L glass graduated cylinder or other pyrex glass container. The YouTubers use 20-Volume hydrogen peroxide, which is a 6% solution that's stronger than the kind found in pharmacies or drug stores. Add 5 mL dishwashing liquid and 10 drops food coloring to the graduated … Materials: 30% H 2O2 1 L Graduated cylinder KI or NaI Food coloring Liquid dish detergent Large bin Procedure: 1. The potassium iodide in Uhas and Dobrik's experiment is a more powerful catalyst that produces an explosion effect, as opposed to the rising foam that filled Rober's pool. Science YouTubers are engaging in a bit of a "foam arms race" this week with gargantuan versions of the elephant toothpaste experiment. If you have enough materials on hand, you can try different variations of the experiment like Rober did in his video — or see how much foam you can produce by increasing the quantity of materials. Another important thing to note is that the reaction is exothermic, meaning that the foam will be hot. If using a funneled top, you should definitely do the experiment outside, because the stream can reach several feet in the air. Our EXTREME Scientists do the Elephant’s Toothpaste demonstration in our Extreme Science Theater located on the lower level of the science center. Saturated potassium iodide (KI) solution Liquid dishwashing detergent Food coloring 500 mL graduated cylinder Splint (optional) We pour potassium iodide solution into hydrogen peroxide solution to form elephant toothpaste He combines it with three or more tablespoons of warm water in a separate small container, and mixes it for about 30 seconds, until the mixture has the consistency of "melted ice cream."
