Color-Changing Wibbly Wobbly Stuff
Acids are pink, Bases are blue, You wanted an indicator, And we've got one for you!
Color-Changing Wibbly Wobbly Stuff can be used to determine if any liquid or solid is an acid or a base in class and is completely safe for young students. This indicator is completely natural, unlike most other indicators, and works just as well. It's a blend of red cabbage and water that detects acids by turning pink, and bases by turning blue. When it's neutral, it's purple. It's a great, organic, and fun way to jazz up your science class!
