"Describe a captivating scene as attendees enter the room: Upon entry, they encounter buckets inviting interaction. Markings on the floor indicate where to place the buckets, triggering a simulated water-filling effect. As the buckets are placed, NFC sensors activate, accompanied by the sound of water, while LEDs illuminate within the buckets, mimicking the filling of rainwater. This immersive experience serves to raise awareness about water conservation, engaging participants in a tangible way to emphasize the importance of saving water."
