“We have a device which changes any phone or tablet into a 25-times enlarging microscope,” Oceans Institute artist in residence Angela Rossen said.
The CSIRO Floreat-based environmental educator will demonstrate the phones during the Less is More Festival when it is launched at 10am at The Grove library, Peppermint Grove, on June 25.
“The children can have a close look at marine plants, the plastics in the sand and its effect on the tiny creatures of the ocean,” Ms Rossen said.
The festival will also launch Plastic Free July, which encourages people in the western suburbs to avoid using plastic for the entire month.
