It sound like an odd request but Vivid Sydney wants to repurpose any spare glomesh bags and lava lamps you might have stuffed in the wardrobe. Why, you ask? It wants to create something magical.

From May 25 Light Market, a pop-up sensory experience, will be happening in Chatswood – a major Vivid hub.

Inspired by the intricate architecture of Brazil’s shanty towns, or favelas, the food-and-light market will be built using items collected over months – including the donated lamps and bags – arranged into stalls.

The organisers aren’t giving much away about what snacks will be available, but Willoughby City Council’s mayor, Gail Giles-Gidney, says: “The food will be great, featuring incredible desserts, gourmet burgers and amazing Asian.”

The Light Market has been designed by Geoff Cobham (who is behind Blue Bottle Lighting and Design) and built by Light Market producer Victoria Harbutt and Sydney-based scaffold-sculpture artist and Light Market production manager Alejandro Rolandi.

The family-friendly interactive experience will be located at Victoria Ave, Chatswood CBD, Chatswood Mall and the Interchange.

If you have a lava lamp or glomesh bag in your possession, then take it to Willoughby City Council located at Level 4, 31 Victor Street Chatswood NSW by Friday, May 4.

Vivid Sydney at Chatswood is a free event that runs from May 25 until June 16.
