The News Minute | October 5, 2014 | 03:46 pm IST Do you often get the feeling that your bag of potato chips is filled with more air than chips? What you could also do with it- apart from the obvious choice of eating it- is make a raft and row across a river. Sounds wacky?Well, this is what exactly a group of friends from South Korea did recently- they tied 160 packets of unopened packets of snacks and made a raft. The result being that two sat on the raft and paddled 1.3 km across the Han River, states a report by the BBC. According to the report, manufacturers say that it is important to fill the packets with some amount of nitrogen to protect the contents in it.
