You already know I love fire; safe, controlled, fire. Today's experiment involves fire and creating black "snakes" with a few things you - hopefully - have on hand. Have fun watching this chemical reaction between baking soda, sugar, and heat. Kids - this is one that requires an adult to be present (although do your best to convince them to let YOU do the experiment if you are at in 2nd grade or higher). You also have to do this one outside. Materials:
Parent Tip: Be sure to do this experiment outside and on a glass, metal, or concrete surface and be prepared to leave the bowl for a bit to cool down. How To Links: Here is the link to the instructions and video. Thanks to Home Science for this activity. If you prefer written instructions, Hooked on Science provides them here. What's Happening: When baking soda is heated, carbon dioxide gas is created. The formation of gas causes an increase in pressure which leads to expansion of the material into it's snake-like configuration. Each new piece that reacts is adjacent to the previous piece thus pushing up the previous material and connecting to it. The snake is black because when sugar is burned (caramelized) it turns black (you can test this by using your lighter and burning a small scoop of sugar). A more detailed explanation can be found at the bottom of this link from KiwiCo. Share Your Experience: If you do this experiment feel free to post pictures in the comments section below. Happy Sciencing!

welcome!
Every school day I will post a new experiment for you to try at home. Some may be familiar to you - as they are my favorites from class - but most will be experiments I found on the web that have readily available materials. Happy Sciencing! Earn a Patch
