Cat's eyes

The transcript describes how Percy was inspired by a cat's eyes reflecting light to invent a road safety device called cat's eyes. These devices use glass balls with a reflective substance to help drivers see the road at night. Percy also developed a self-cleaning mechanism using rainwater to keep the glass clean. Over 80 years later, cat's eyes are used worldwide, contributing significantly to road safety alongside other reflectors.
