You can buy test strips or a digital pH meter. Just dip, wait, and compare the color to a chart. Pro tip: don’t test water right after a storm—rain creates carbonic acid and throws off your reading.
And no, you can’t tell the pH by looking at water. Unless it’s blue or purple (please don’t drink that), color is a liar. Trust the test, not your eyes.
Fun Fact: pH and Your Taste Buds
Ever notice that alkaline water tastes "smoother" to some people? That’s because your tongue feels less acid burn. It’s like the difference between a friendly handshake and a wet fish slap.
