The star sometimes appears brighter,and at some other time, fainter, which is the twinkling effect.
A rain stick can give that effect. It's a percussion instrument.
It's percussion because the strings are hit with hammers. It can be classified as a percussion or string instrument.The piano is in the percussion family because the sound is generated from little hammers and wires inside. When you press a piano key, the hammer hits the wire, producing sound. The action of the hammer hitting the wire is what classifies it as a percussion instrument, like when hit hit a mallet on a bell kit.
The triangle is a percussion instrument. In orchestra, it is simply used as an effect.
Outerspace ... the twinkling effect happens when observing the star(s) through earth's atmosphere. If you were in space, they would not twinkle.

Yes ... and no! Yes, because it has strings ... No, because the method to produce sounds uses a percussive effect, therefore, it is technically it is a member of the percussion family, as well as the string family.
Calcite has a uniaxial indicatrix with a ellipsoid shape. The two permitted vibration directions (transmitting the ordinary and extraordinary rays), cause twinkling to be observed on rotation.
