It might sound like an old wives’ tale, but carrying a potato in your car could have unexpected benefits, especially in emergency situations. Here’s a closer look at how something as simple as a potato can be surprisingly useful and potentially lifesaving when you’re on the road.

**1. Demisting the Windshield: One practical use of a potato is its ability to demist car windows. Potatoes contain starches that, when rubbed on window surfaces, create a barrier that prevents condensation. In cold weather, when windshields and windows often fog up, a cut potato can be rubbed over the inside of the glass. The layer of starch it leaves behind works to disperse condensation and keep your windshield clear, enhancing visibility and safety while driving.

How to Use:

• Cut a raw potato in half.
• Rub the cut side of the potato on the inside of your car windows before you start driving.
• Wipe away any excess moisture with a cloth, leaving a thin starch layer.

**2. Emergency Food Supply: In extreme situations where you might be stranded, a potato can serve as an emergency ration. Potatoes are nutritious, containing carbohydrates, vitamin C, and potassium, which can provide essential energy in a pinch.

**3. Natural Ice Preventer: Similar to its use for demisting, the starch from a potato can be applied to your car’s windshield and windows the night before to help prevent ice from forming. This can save you significant time defrosting your car in the morning and offer a quick start in freezing conditions.

**4. Signal for Help: In an emergency where you need to signal for help, a large object like a potato can be useful. You can create an SOS or help signal on the ground in an open space using potatoes, which are visible from above and can last longer than leaves or other perishable markers.

**5. Fire Starter: While not widely known, the chemical reaction between the glycerol in a potato and potassium permanganate (if you happen to carry it for purifying water or as a part of a first aid kit) can start a fire. This can be critical for warmth or cooking in survival situations.

Conclusion: While the idea of keeping a potato in your car might seem quirky or unconventional, its versatility in practical and emergency scenarios can be incredibly helpful. From keeping your windshield clear to potentially aiding in survival situations, a simple potato could indeed be a lifesaver on the road. It’s a low-cost, multi-functional tool that’s worth adding to your vehicle’s emergency kit.4
