Prompt
/imagine prompt: A professional, high-resolution YouTube thumbnail featuring a smiling, surprised man on the left side of the frame [SUBJECT_REFERENCE_HERE]. The background is a bright, clear blue sky. In the center of the frame, held by the man's hands, is a detailed, skeletal-frame DIY gadget (a clear acrylic casing revealing internal components like a blue battery and a large silver heat sink). This gadget is actively firing a powerful, arcing blue electrical bolt from its red barrel towards a large, splintering tree trunk on the right side. The tree bark is visibly charred and splintered at the impact point. Above the gadget, centered, is a white, rounded rectangular card element containing a 5-star rating graphic (5 large, bold yellow stars) and the exact text: "cool gadgets" in black, sans-serif font. The lighting is bright and direct daylight, making the electrical discharge and the gadget's components pop. The overall composition is clean, trustworthy, and urgent, optimized for high engagement. --ar 16:9 --v 6.0
