Vibsky Wind Tunnel Model Smoke Visualization Tester for 1:641:43 Scale Cars

• 💨 SEE THE AIRFLOW — Pure water mist traces clean, residue-free streamlines over your model, so die-cast collectors, RC hobbyists and STEM teachers can watch aerodynamics in action on a desk or classroom bench without ash, odour or smoke stains.
• 🎛️ DIAL IN ANY SPEED — One smooth stepless knob takes airflow from a gentle breeze to a strong steady stream, letting hobbyists and students mimic slow city cruising or high-speed track runs on the same 1:64 or 1:43 model at a quiet under-35 dB.
• 🚗 FITS 1:64 & 1:43 CARS — Engineered for die-cast models in both scales, it turns a shelf into a demo rig for collectors, club members, teachers and students running airflow tests, science fair projects or gift-day show-and-tell. Model car not included.
• ⚡ SAFE LOW-VOLTAGE MIST — Runs on a 5V / 2W USB supply (cable included); the 60 ml tank gives about 20 minutes of fine mist per fill, and the low voltage keeps both hobbyists and their delicate die-cast collections out of harm's way. Rinse the nozzle after use.
• 📐 DESK-SIZED & LIGHT — At 25 x 7.5 x 11 cm and 480 g, this white PVC unit sits on a garage workbench, classroom science desk or home office shelf, ready for club demos, show-and-tell or a weekend build session without taking over the table.

Features: 1. Visualized Airflow: Uses pure water to create a clear airflow trajectory, easy to observe and residue-free. 2. Adjustable Airflow: Equipped with a stepless control knob, it can simulate various driving conditions from city cruising to high-speed driving. 3. Compatible Design: Suitable for 1:64 and 1:43 scale car models, and can be used for various aerodynamic tests and demonstrations. 4. Safe Operation: Employs a low-voltage for power supply and water for mist system to for ensure user safety and model protection. 5. Realistic Simulation: Simulates the principle of an industrial wind tunnel, outputting stable airflow for accurate aerodynamic analysis.
