Build a Levitating Magnetic Cube in a Tube Prototype for Viral Promo

---

The Goal: A black cube levitating inside a clear tube, powered by hidden magnets or gravity-guided alignment, with lighting above and below—and a QR code that’s only visible under blacklight. The Build Requirements: Levitating Cube in Tube Design: - The cube must automatically float in the center when the tube is placed on a flat surface and the switch is turned on. - We're open to using gravity-based resting or weaker guiding magnets to ensure alignment before levitation starts. - Tube should be clear acrylic or similar for full visibility. - Black Cube with UV-Revealed QR Code: - Cube can be matte or glossy black. - QR code should be invisible in normal light and only revealed under UV/blacklight illumination. Integrated Lighting: - Include subtle UV LED backlighting from above and below to illuminate the cube in a sci-fi, sleek way. - Bonus if it can subtly pulse or glow without overpowering the levitation effect. Power + Switch: - Must include an internal battery pack (rechargeable preferred). On/off switch is required to prevent battery drain during shipping or storage. - Ideally has a charging port that doesn’t ruin the aesthetics.
