Many people just don't have the same zeal for soccer as rugby. But if a giant 1.8m wide helium-filled soccer ball were used instead of those regulation balls, maybe more people would tune in here to watch the World Cup.
You can actually buy this giant ball from VAT19 to spice up your own soccer games. It's just $US100 for an inflatable toy that's 91 times as large as your standard beach ball, and from the looks of it, at least that many times more entertaining. But the helium costs extra, and there might actually be far better uses for it given the gas is becoming so scarce.
