Turns out that high-school chemistry isn't as useless as some may think.<br /><br />Watch closely as Morgan McKeen reveals an easy way to make invisible ink. <br /><br />She starts off by dissolving 1 tablespoon of baking soda in a half cup of water. Then, in another cup, she mixes turmeric and hand sanitizer. <br /><br />For the next step, she recommends writing or drawing with the baking soda mix, allowing it to dry, and then painting over the text/drawing with the sanitizer/turmeric blend. <br /><br />"A spooky Halloween craft using science to create invisible ink," Morgan said. "Turmeric is a natural pH indicator and changes color when combined with baking soda."<br />Location: Auckland, New Zealand <br />WooGlobe Ref : WGA895072<br />For licensing and to use this video, please email licensing@wooglobe.com
