Leah Nesbit started off with a paperclip.
Now, she has an ice cream maker. By Sunday, she hopes to have an item of such high quality it will fetch a significant amount of money for victims of Christchurch's shootings.
The Tauranga primary school teacher has embarked on The Paperclip Challenge, aiming to trade up a paperclip in seven days to something valuable.
Within two days, the paperclip has already been traded for a whistle, pen, stationery set, hat, Warriors shirt, tennis racquet and today the ice cream maker.
