Most kids and parents will be familiar with Zuru's Bunch O Balloons toy, capable of filling and tying 100 biodegradable water balloons in a minute - every child's water fight dream.
The toy has been the number one top seller in the US for the last three months over summer.
Not so well known however is that the company is founded and run by Kiwi sibling trio Nick, Mat and Anna Mowbray.
Nick Mowbray, president and director of Zuru said the idea for the company originally came from his brother Mat's science project, a hot air balloon kit set that won him a national prize and Mowbray said it grew from there.
"You have to start somewhere so it started really small, just knocking on doors, selling these little kit sets," Mowbray said.
