Make a chemical indicator from kitchen items

In this tutorial, we learn how to make a chemical indicator from kitchen items. First, make an indicator by grabbing some red cabbage and some vodka. Now, heat up some water until it's boiling, then place a smaller beaker inside the water with vodka inside of it. Place the red cabbage inside of the smaller beaker, then stir it up and let sit for 10 minutes. A lot of the color will come out with the cabbage being inside of the alcohol. After this, pour this into a storage bottle and pour the water into a flask. Then, pour in some acid to this and then drip in sodium hydroxide solution. The solution will turn red, green, then a yellow color as it continues to drip into the container. These are great indicators that work well and use only items from around your kitchen!
