DISCOVERY Science and Technology Bendigo science communicator Rachel Rayner knows how to make an annoying sound.
And these school holidays she is telling students exactly how to make them.
Ms Rayner has been leading the Sounds of Science show at the Discovery Centre where she explains how sound works and how to make it using whirling tubes, things that explode and even fire.
One of the highlights of Ms Rayner’s show is the Reubens Tube, which shows how sound frequency looks as a standing flame.
But in the planetarium there is a much quieter affair.
The Silence of Space show explains how the vacuum of space refuses to let sound travel and what some of the silent features of the sky are.
After learning how to make sounds, children can even try making their own instruments at the Making Music workshop which runs from 12.30pm to 3.30pm.
The Sounds of Science is on each day at noon and 2pm. The Silence of Space is on daily at 11.30am, 12.30pm and 1.30pm.
