How can you make a highlighter ink from turmeric extract?

To make a highlighter ink from turmeric extract, mix turmeric powder with a small amount of water to create a thick paste. Then, add a few drops of vegetable glycerin or corn syrup to enhance the ink's consistency and brightness. Strain the mixture through a fine mesh to remove any solid particles, and store the liquid in a small container. This natural ink will produce a vibrant yellow color, perfect for highlighting text.
