Features:
1. Realistic Flow: Simulated particles behave like real sand under gravity, continuing to fall downward even when inverted.
2. Power Supply: Dual-mode power via Micro USB + external battery support for convenient and quick use.
3. Gravity Sensing: “Sand grains” on the electronic screen flow under gravity, creating a unique visual effect.
4. Customizable Countdown: Set freely from 01 to 99 minutes via buttons. The hourglass automatically adjusts flow speed for precise timing.
5. Shipped as loose components requiring self-assembly. Ideal for maker electronics DIY, science outreach, educational displays, and similar applications.
