Textbooks typically use gas burners or alcohol lamps, but using an open flame in your living room is a bit challenging, right? Concerns like &#8220;difficulty controlling the heat&#8221; or &#8220;danger of tipping it over&#8221; might cause people to hesitate before trying the experiment.<\/p>\n<p>The revolutionary item that solves this problem, taught to me by science education specialist Mr. Eiji Komori, was none other than an &#8220;Electric Jar (Rice Cooker)&#8221;.<\/p>\n<p>The idea is to fill an old rice cooker with hot water, set it to the &#8220;keep-warm&#8221; mode, and place your test tube inside to heat it. Essentially, you use it as a safe &#8220;water bath (Bain-Marie)&#8221; apparatus. This way, you can maintain a constant temperature without using an open flame.<\/p>\n<h3>The &#8220;Ultimate Lab Tool&#8221; Discovered by a Science Teacher<\/h3>\n<p>The electric rice cooker is certainly a convenient, fantastic idea\u2014lower burn risk and easier to implement than a gas burner. However, I didn&#8217;t have a spare one at home, and few students I asked owned one either. While searching for a substitute, my eyes fell upon an appliance collecting dust in the back of my own shelf. &#8220;This is it!&#8221; I thought. It was an Electric Pot (Grill Pan).<\/p>\n<p>An electric pot allows for fine temperature control, from warming to heating, and has a wide, user-friendly opening. Convinced, I immediately donated one to the school science lab and introduced it.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25399 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/06\/607ead9ec2ef3a493216fb98e6be5d2b.jpg\" alt=\"\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8 2016-06-30 23.02.31\" width=\"575\" height=\"437\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/06\/607ead9ec2ef3a493216fb98e6be5d2b.jpg 575w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/06\/607ead9ec2ef3a493216fb98e6be5d2b-300x228.jpg 300w\" sizes=\"auto, (max-width: 575px) 100vw, 575px\" \/><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/amzn.to\/3JT4kRP\">Zojirushi Electric Grill Pan<\/a><\/p>\n<p style=\"text-align: left;\">I use the Zojirushi Electric Pot.<\/p>\n<h3>An Excellent Stand-In for a Laboratory&#8217;s &#8220;Constant Temperature Bath&#8221;<\/h3>\n<p>In practice, it became a huge hit even in the science lab. In scientific experiments, the apparatus used to maintain a substance at a fixed temperature is called a constant temperature bath; the electric pot functions perfectly as a simple version of this.<\/p>\n<p>Three Reasons Why the Electric Pot is Ideal for Experiments:<\/p>\n<p>Easy Temperature Control: It can be preheated or kept at a steady warmth, making it easy to standardize conditions for experiments like solubility studies.<\/p>\n<p>High Safety: Originally designed for tabletop cooking like hot pot or yakiniku, it has a sturdy guard around the edges and a structure that keeps the exterior from getting too hot.<\/p>\n<p>Excellent Stability: Its flat shape means you don&#8217;t have to worry about it tipping over, unlike a gas burner or alcohol lamp.<\/p>\n<p>As shown in the photo, you can fill the electric pot with water to create a hot water bath and place test tubes in a beaker inside it for heating. Direct heating can risk sudden boiling (bumping) or even cracking the glass, but this &#8220;water bath method&#8221; heats the substance gently, making observation easier and the process much safer.<\/p>\n<h3>Conclusion: Enjoy Science with What You Have in Your Kitchen<\/h3>\n<p>When conducting experiments at home, be sure to utilize this &#8220;Electric Pot.&#8221; Since it uses no open flame, you can focus on the experiment safely, reducing the worry of burns even when working with small children. While it&#8217;s certainly handy as a piece of lab equipment, it&#8217;s also a star at home parties for hot pot or yakiniku (^^) Why not start by enjoying a delicious meal cooked in the pot, and then follow up by having the whole family enjoy a &#8220;White Christmas&#8221; with the ammonium chloride recrystallization experiment?<\/p>\n<p>Science isn&#8217;t just something that happens in special places. Finding creative ways to use everyday tools is a crucial part of scientific thinking!<\/p>\n<h3>Inquiries and Requests<\/h3>\n<p>Bring the wonder and fun of science closer to home!
