I received the following from Miranda and her dad via our year 6 support email:
'Miranda and I did a physics experiment inspired by someone she follows on YouTube (Steve Mould). It involves putting a little bluetooth speaker inside a small bowl, with a rubber sheet stretched over the top (nitryl gloves in our case!) That provides a vibrating membrane, and sounds played through the speaker cause the space in the bowl to resonate. We stuck a tiny bit of mirror on the rubber membrane, then pointed a laser pointer at it. With the right pitched sounds, you get lissajous-like figures reflected onto the wall!'
