Time Out says
It's that time of the year again – turn off all electricity for an entire hour for Mother Earth. This year, join City Square Mall in spreading awareness of energy waste. From 4.30pm to 10pm, indulge in a line-up of fun and exciting activities suitable for the whole fam.
Pledge to save water with special guest Water Wally at the water conservation roadshow, participate in a bottle piggy bank-making workshop using recycled materials, test your water conservation knowledge to stand a chance to win attractive prizes, and when the lights go down, nestle in the darkness for a screening of Disney's Moana.
