Discover acid-base colour changes, use the heat from their hands to make colours appear on paper and perform colour-changing chemical magic.
Young scientists will use the heat from their hands to make colours disappear on this special paper. Determine if your hands are warm enough to make the colour change or if you need a little friction to warm up. We’ll show you how to use this colour-changing paper to develop a hidden message and make your handprint appear right before your eyes.
