How the trick is supposed to work1. Positioning: A transparent water bottle is wedged in the wiper slot, catching sunlight.
2. Physics claim: Some say the water acts like a prism, refracting light and reducing heat buildup.
3. Result: Proponents argue the interior temperature drops noticeably, making the car cooler when you get back in.
What experts say- No scientific backing: Most automotive experts dismiss the technique as a myth; the bottle does not significantly alter cabin temperature.
– Potential risks: The bottle can obstruct wipers, cause scratches on the windshield, or create a distraction while driving.
– Better alternatives: Using sunshades, tinted windows, or parking in shade are proven methods for reducing interior heat.
Practical adviceIf you want a quick cooling effect, skip the bottle hack and try these simple steps:
– Roll down windows slightly for ventilation (if safe).
– Use a reflective windshield cover.
– Turn on the air conditioner or fan as soon as you start the engine.
