Death of a Gummy Bear

gummy bear and potassium chlorate reaction

However, it is quite reactive with the gummy bear! K + and Cl - have opposite charges and have a force of attraction between the cation and anion, which is called an ionic bond. Potassium chlorate will ignite when exposed to anything even slightly flammable. Heat it until the powder in the tube is completely melted. For convenience sake, both the Joule and calorie are often expressed in multiples of 1000. So I power my everyday activities like dancing and running, but I don't explode.

How to Perform the Dancing Gummi Bear Demonstration

The mixture of potassium chlorate and sugar is a simple form of sugar rocket fuel. Students chuckle, mumble about me being crazy, accept that it will likely be a cool demonstration, and get ready to work. Students should not be close to the reaction. The color of the light is familiar to us, from the reaction of metallic potassium with water. The heat produced continues to decompose the potassium chlorate resulting in a very rapid combustion reaction. Within limits, energy may be controlled to appear as heat as we use electric power to dry clothes in a dryer or work the same electric power rotating the drum in the same dryer.

I don't want to think about that but I'm going to need the energy. I ask them to say goodbye to the evil little gummy bear witch, and go into the storeroom to heat the potassium chlorate. Uses for sugar Adding sugar and vinegar into flower vases with the water helps the plant look nice for a longer amount of time Sugar can help soothe a persons mouth after eating something spicy Sugar can be used help heal painful infections this has been done for many years Exfoliates skin well A paste of sugar and water can get rid of grass stains Putting sugar on a burn on your tongue can ease the pain. Why did I never do this in chem class when potassium chlorate was available to me? The exact amount isn't important. Students have gotten very good at calculating molar masses, so this is a completely independent activity. We fill in the dimensional analysis like this: I stress to students that they absolutely have to fill in their units each time, so that they know when to put grams on top or bottom, and when to change chemicals.

At room temperature and pressure, the salt exists as a solid. So, while some may call us cruel for this, we decided to sacrifice Bob, a. In some classes, students ask why and I explain that in the 1600s, it was common knowledge that bears were spirit animals of witches, and since witches got burned at the stake, that we must follow tradition and burn some evil gummy bears. Flush eyes immediately with water if any chemical gets in your eyes. Now by looking at the number of bonds and the type of bonds, so a carbon bonded to an oxygen, or a carbon bonded to a carbon, and a single bond versus a double bond, you can calculate the energy difference between the left side of the reaction, the reactants, and the right side, or the products. When everyone has finished the quiz, I ask students to share their molar mass values so students can all have the same starting information.

What's In A Name? Part 1: Comparing KCl(aq) and aqeous potassium chlorate reactions with aqueous silver nitrate; Part 2: Comparing hot KCl vs potassium chlorate reaction with sugar

Evolution has trained biological systems to efficiently extract energy from our environment. They will not be removed unless a moderator deems the repost to be of a demonstration or particular gif that has been posted too often e. And now I'm going to do this same reaction inside of a test tube. The reaction that Bang explains is something that is recreated in many high school chemistry classrooms and science museums across the country. Concentrated sulfuric acid is a strong dehydrating agent and should be handled carefully. As students finish, they come up and turn the quiz in and take our sheet, and I ask them to begin working on the molar masses at the top of the page.

Alternatively, perform this demonstration outdoors. Those carbohydrates will react with oxygen, occurs. Bleach pens is pure sodium hypochlorite. Also — as mentioned at the start — when science is blended with fiction, what ethical guidelines should be adhered to? This makes an exothermic, combustion reaction. I begin by having students share the molar masses they calculated for our six chemicals. Spills should be neutralized and wiped up.

Gummy Bear meets Potassium Chlorate Experiment

Write the balanced equation for the reaction. Since we were the most explosive experiment, we started the experiment shindig with a blast, or, to make it more technical, with a rapid oxidation reaction. After doing our y, we spent an extra day just working on practicing the problem setup and mathematics. The heat, evolved or required is the change in enthalpy. Combustion is a typical exothermic reaction any type of burning. An eye-dropper of aqueous 1.

Gummi bear explosion (and other experiments)

gummy bear and potassium chlorate reaction

In such oxygen-rich environment with sufficient temperature, gummy bears burst into a lilac flame vigorously when in contact with the molten chlorate. Among other things, the experiments should include the following safety measures: a high level of safety training, special facilities and equipment, the use of proper personal protective equipment, and supervision by appropriate individuals. Clean up is not the easiest because there are charred bits stuck to the test tube. It turned from a solid to a liquid. Avoid contact with flammable materials. Procedure B: Perform in the Hood! What are we asked to find? We expect the original poster to do this, however if someone else does so then it will not be removed.

Chemicals (commodities): Why does a gummy bear react with potassium chlorate?

Use care when removing the potassium chlorate from its container, to avoid sparking, which can ignite the container. Understanding: Our experience with salts is that they are solids. Woodrow Wilson National Fellowship Foundation Website: Warning: The ethical ramifications of research on Gummi animals are very controversial. The reaction produces a sweet burnt smell. Clifton's going to play a little rondo or music while I set this reaction up.

Nothing happens, no reaction occurs. Here's a simple fire chemistry demonstration that produces instant fire without using matches or any other type of flame. So here are the reactants and here are the products. Before passing out the quiz, I explain that there are four problems for them to set up and solve. How much water is produced after fully burning all the sugar according to the equation above? Place a small quantity of potassium chlorate in a test tube. The difference is that proteins in my body are set up in pathways that extract the energy in small, manageable bundles.
