Charlie Loretan (3), of Dunedin, is proud of his creation, a jetpack he crafted at the Dunedin Public Library yesterday.
The rocket-building exercise, one of 150 Dunedin events that are part of the New Zealand International Science Festival this week, attracted 40 children.
International Science Festival associate director Andrea Liberatore said she was thrilled to see children show their creative sides.
"It’s the sort of thing that lays the foundation for their curiosity, which is so important."
It was amazing to be able to hold a "nano festival", she said.
"Covid-19 meant we cancelled everything for a start, before realising we could actually hold some events."
