At over 19 meters tall, this colossal yellow bath toy is higher than a six-story building!

What happens when bath time goes supersized? In 2025, the creators of the popular "B. Duck" characters built a bright yellow bath toy that would make an Olympic swimming pool look like a tiny puddle.

Claiming the record required exact measurements using professional surveying equipment. When the judges checked the math, this colossal inflatable duck towered a jaw-dropping 19.08 meters into the Shenzhen sky, officially claiming the crown.

Keeping a balloon this gigantic from blowing away is a serious engineering challenge. The team used industrial-strength fabric, massive concrete anchors, and powerful fans pumping non-stop air to keep its cheerful, chubby cheeks perfectly plump.

How Is That Even Possible?

Keeping a 19-meter balloon safely grounded is pure physics. Because a structure this large acts like a massive sail in the wind, engineers must use extremely heavy concrete weights to tether it. Meanwhile, industrial blowers continuously pump air inside to maintain high internal gas pressure and keep the duck's shape.

Wow-o-Meter

A jubilant scene in a city plaza where a colossal, bright yellow rubber duck towers into the sky. The proud creators stand at the base, beaming in triumph while a cheering crowd of kids and judges with clipboards throw confetti into the air. Huge industrial fans and thick anchor ropes are visible around the duck's base, while a flock of tiny real birds flies around the inflatable's massive smiling beak in awe.
