๐ฏ Your mission
Run the experiment. Find out what really happens.
โก The twist
Color changes mean atoms are rearranging โ even if you can't see them.
Mind = Blown
๐ Every color you see is your brain inventing a translation of light frequencies.
Make a hypothesis first
Before you mix: what color do you think it'll turn?
