How do you refill water speakers?

To refill water speakers, first, unplug them from the power source to ensure safety. Locate the fill hole, usually found at the back or bottom of the speaker, and use a small funnel to pour distilled water into it, being careful not to overfill. After refilling, securely close the fill hole and reconnect the speakers to the power supply, allowing the water to circulate and create the desired visual effects.
