Too Much Air in Potato Chip Packets? Students Make a Boat to Prove It

Ever get that feeling when you open a bag of potato chips that you’ve mostly paid for air?

A group of South Korean college students have, and to prove their point, on Sunday they used a raft made of unopened potato chip packets to traverse Seoul’s main river.

Two male students crossed the Han River on a boat made with 160 unopened bags of potato chips bound together near 0.8-mile-long Jamsil Bridge in the city’s east.

The stunt attracted nearly 200 people, according to local accounts.

South Korea consumer groups in recent years have said local food companies are including too little edible product and increasing the size of empty space inside packaging.

Blog posts and online bulletin board entries regularly compare packages of food products such as chocolate chip cookies and crackers. South Korea’s food companies have said the extra space is needed to prevent physical damage to the product.
