Explosive experience

Otago Polytechnic Trades Academy student Poppy Forest, 17, of Dunedin, holds her bath bomb (top) and an exemplar made during a workshop at Lush.

This week, 32 high school students studying beauty therapy through the trade academy made sustainable bath bombs during the workshops.

Tutor Sara Parker said the workshops, part of a unit on sustainability, were a highlight for the students.

"It provides a unique opportunity for the girls to gain knowledge and experience in sustainable practices in the beauty industry."
