An adults-only night at the Discovery Centre means you don't have to feel bad for playing with the exhibits or worry you're taking away time from a kid's first trip to the science-focused spot. This time around, the evening focuses on the centre's latest exhibit, Survival of the Slowest, which sees a live green iguana, sloth, veiled chameleon and more chillin' in enclosures and providing a case for a more leisurely pace. An on-site cash bar adds to the fun.
