Universal indicator

Okay, imagine you have a magic stick that can tell you whether the water you are playing with is safe to drink or not. This magic stick is called a universal indicator.

When you dip this magic stick into the water, the color of the stick changes based on how acid or basic the water is. Acidic water makes the stick turn red or orange, while basic water makes the stick turn blue or green.

So basically, if you want to know if the water is safe to drink, you can use this magic stick to check if it's acidic or basic. If the stick turns blue or green, that means the water is safe to drink. If the stick turns red or orange, that means you should not drink the water because it's not safe for your body.

The universal indicator is like a superhero that helps people understand the pH level of the water they are dealing with so they can make safe decisions.
