Have you tried this NEW Invisible Ink experiment?? #scienceexperiments

Many of the invisible ink experiments involve lemon juice and fire. Luckily, this recipe doesn’t require any heat and is totally safe.

Material Needed:
Warm Water
Baking Soda
Q-tip
Turmeric
Sanitizers
Brush

Science behind it:

Baking Soda ink changes colour when it reacts with turmeric. Turmeric is a ph indicator. This means that it will change colour of different substances when it interacts with them to show us what their ph is.
