is kinetic sand flammable
So, when the methanol was poured onto the smoldering cotton balls, if they were at a temperature above 464 °C, the methanol would instantly burst into flames on contact. James R. Macdonald Laboratory, July 14, 2009: [accessed Sept 2015]. Chemistry at Home –Food coloring: If you managed to find white sand, you can color your own kinetic sand the way you like it. By reading the information contained in the SDS, the highly flammable nature of methanol is revealed. This sand is silky, soft and odorless. Learn about financial support for future and current high school chemistry teachers. Despite being made of (mainly) natural materials that make it non-toxic, Kinetic Sand still presents some risks. chemical bonds, the properties of water molecules, and organic chemistry), which are often perceived by students as heavy and boring, emerge spontaneously as part of the inquiry into the mysteries of magic sand. – Sand: of course, this needed to be here. Firstly, it seems that this sand is always wet, and yet it never dries out. Alternatively, the teacher can demonstrate the behaviour of the magic sand, as shown online, Based on the story, the students will start to compare the magic sand with the normal sand. Even though most people should know better than to pour a flammable liquid onto an open flame, sometimes even trained professionals make this mistake with methanol, with disastrous consequences. Calculated results largely agree with the experimental data, for both the lean and rich limits, except for excessively thick flames for which the limits could be qualitatively affected by radiative heat loss. In the past, we didn’t have expensive toys and we had a great time, right? )@400����q30zgA�_ R�%& In a different bowl, add 1 teaspoon of water and 1/2 teaspoon of hand soap. Fortunately, there is a system in place to provide ready access to this type of information. Kinetic Sand is also used for its soothing effects for triggering Autonomous Sensory Meridian Response or ASMR for short. It is these vapors that will ignite, if enough heat is applied. Provide water and droppers and ask the students to build sandcastles with both samples by wetting the sand. How is it possible to ignite methanol without an actual flame? Kinetic Sand is a great toy for your kids to be creative with. We may be compensated if you make a purchase after clicking a link. OSHA mandates that all workers exposed to chemicals have the right to know about the potential hazards of these chemicals. Rude Science have a great write up about kinetic sand and silicone oil, here is what they had to say: Kinetic sand is made of 98% sand and 2% Polydimethylsiloxane, and it resembles properties of wet sand. American Association of Chemistry Teachers, Reactions: Chemistry Science Videos & Infographics,,,, How to Make Chemistry Classroom Demonstrations and Experiments Safer, Safety Data Sheets: Information that Could Save Your Life. Could these accidents have been prevented? The problem-solving process in TEMI is based on the 5E model of inquiry learning, which structures the learning process into five phases: engage, explore, explain, extend and evaluate. If methanol is at or above its fire point, it will continue to burn when lit. 49 0 obj <>/Filter/FlateDecode/ID[<7F7B58C9ACA10441AEBE499AB818593B>]/Index[30 31]/Info 29 0 R/Length 91/Prev 51667/Root 31 0 R/Size 61/Type/XRef/W[1 2 1]>>stream Kinetic Sand is a fantastic product used for kids play and STEM learning and education. For a more complex answer about how kinetic san actually works from a scientific standpoint, we have had to do some research, and consult some experts. Section 2 of the SDS is labeled “Hazards Identification.” A typical listing for methanol under this section may read as shown on the left. Here is a great video about how Kinetic Sand works. If you would like to get kinetic sand I recommend this one on Amazon. IV. So, for parents who are concerned about the possible health risks of this toy, I would advise them to be careful. The study further show that H+O2O+OH is the dominant branching, reaction for all lean and rich limits, that H+O2+MHO2+M is the dominant termination reaction for all lean limits, that the dominant termination reaction for rich limits can be mixture specific, and that as the flammability limit is approached the maximum termination rate occurs in the same physical region as that of the maximum branching rate, thereby allowing for the most efficient radical scavenging. Made out of 98% regular sand and 2% polydimethylsiloxane, kinetic sand’s unique moldable properties, as well as the ability to never dry out, make it the perfect toy for kids to experiment with and use their imagination. ... As a liquid warms, the average kinetic … Where can teachers (and students) find the type of information needed to use chemicals in a safe and responsible fashion? Many accidents involving methanol occur because it is poured onto an open flame. But, despite the age recommendation, it is always advisable and important that an adult supervises the use of kinetic sand, because there exists a risk to your kids’ safety in the case of their ingesting large quantities of it. Water forms droplets to a "ball" of CoolSand will sit on my counter, but Kinetic Sand will probably crumble and melt just from the pressure of putting it down) Both KS and CS "flow" about the same when in their soft state He took a bucket of water and poured it over the sand, but something really strange happened: the sand would simply not get wet. -This sand is wheat, gluten and casein free, which makes it safe for allergic or intolerant kids, too. Here are some of the ingredients that you will need: –Liquid soap or detergent: the kind you use for dishes, but also hand soap would work.eval(ez_write_tag([[580,400],'lowcostplayground_com-box-3','ezslot_12',105,'0','0'])); –Corn starch: in the case that you don’t have it, flour can be a possible substitute for it, but the texture may vary. There is a great deal of motivation for these companies to be thorough and accurate, as any incomplete or false information could lead to serious harm by the user, not to mention a lawsuit. The autoignition temperature is the temperature at which a substance will burst into flames without an outside ignition source, such as a spark or a flame. He poured some additional methanol onto cotton balls in a dish after the flames had apparently gone out, but the cotton balls were still smoldering and instantly re-ignited when the methanol was added. Let’s look at an example of an SDS for methanol and see if it contains information that could have helped to prevent the tragedies described above. It does not cause burns or severe skin or eye irritation. Kinetic Sand is indicated for children ages 3 and up because smaller kids are at risk of potentially swallowing the sand and choking on it. Kinetic Sand is moldable, but does NOT hold shapes as well as CoolSand. Read through section 5 of the SDS on the left to see if you can figure out why this mistake may occur. The fire point is typically only a few degrees higher than the flash point. The different colored flames produce the so-called rainbow effect, which would certainly impress the students. Brian Rohrig is a science writer who lives in Columbus, Ohio. h�̖�O�8���x�;�_b'�T����QQ�?��m3ҤK��}m��ݸ�t�I�lǏ����G,b1g\)Ƶ`�dX However, it still does move, but just not quickly. Magic sand is different. Every chemical has its own Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheets (MSDS), containing a wealth of information in a simple, easy-to-read format. One update is the adoption of a uniform set of pictograms developed by the United Nations, which is used throughout the world. Fire and Explosion Flash Point: None Auto Ignition Temperature: None Flammable Limits in Air: Not Combustible Special Fire Fighting Procedures: None, may be used t o extinguish fire Unusual Fire and Explosion Hazards: None V. … (adsbygoogle = window.adsbygoogle || []).push({}); Kinetic Sand is regular sand, but instead of being coated in water (like wet sand), it is coated with Silicone Oil.

On YouTube you can find an entire channel dedicated to trying out kinetic sand recipes: DIY Kinetic Sand. The surface of the grains of magic sand is hydrophobic (apolar), so hydrogen bonds cannot form between the sand particles or with water molecules. Explore the interesting world of science with articles, videos and more. If you don’t want to buy kinetic sand, or you simply have a free afternoon and would like to make your own kinetic sand for your kids to play with, there are many recipes which include simple ingredients that you can use to make it. Find a chemistry community of interest and connect on a local and global level. But with a toy that contains silicones and other materials that change the texture and properties, and that stick together (as is the case for kinetic sand), we have to be more careful. Silicon oil is used in lots of products, most commonly for lubricating. %%EOF The trimethylsilanol forms covalent bonds with the hydroxyl (–OH) groups on the sand molecules’ surface, replacing the hydrophilic –OH groups with hydrophobic siloxaneones. Although the label says that both the liquid and vapor are flammable, the liquid itself does not actually burn. Using an everyday toy can introduce mystery into the classroom and help explain chemistry. An SDS meets the requirements of the Occupational Safety and Health Administration (OSHA), a U.S. federal agency created to ensure a safe work environment for all employees. So, the next time your chemistry teacher tells you to put your goggles on, make sure you comply, as he or she is only looking out for your safety. Image courtesy of Ingo Eilks. IBSE focuses on student inquiry as the driving force for learning.
