Did you know? In 2014 Korean students made a raft out of potato chips

In 2014, a group of four South Korean friends tried to prove just how much nitrogen air is stuffed in packets of potato chips. The students agitated by increasing gas content, built a raft by tying together 160 unopened bags of potato crisps. Then two of them stepped aboard and paddled it for 1.3km (0.62 miles) across the Han River, watched by nearly 200 spectators.
