In terms of Physics, we could first consider energy. If you 'play' it by tilting it one way and then the other, then your arm is the source of energy. The beads inside are initially supplied in this way, with gravitational potential energy. As they fall, they lose it to gain kinetic energy. However they continually collide with the spikes, and with each other. In this way, some of the energy converts to sound. Because of the randomness and nature of the collisions, I would imagine that the sound could be described as 'white noise', sound which consists of a wide range of frequencies. The frequencies that would be reinforced would be the ones that would resonate due to the dimensions of the case. That is, the length, and the diameter.
The resonance of a rain stick is created by the sound of small beads or seeds falling through the tube and bouncing off the nails or pins inside. This creates a soothing, calming sound that mimics the sound of rain falling.
A rain gauge measures the amount of precipitation (rainfall) that has fallen in a specific area over a period of time. A meter stick is used to measure the depth or height of the water collected in the rain gauge to determine the exact amount of rainfall.
The driving force behind the principles of physics is the pursuit of understanding and explaining the fundamental laws that govern the behavior of the universe. Physics seeks to uncover the underlying principles that govern the interactions of matter and energy, and to use this knowledge to predict and explain the behavior of physical systems.
The secret behind the physics hand trick that seems to defy gravity is the manipulation of forces and balance. By positioning your fingers and hand in a specific way, you can create the illusion that an object is floating or defying gravity. This trick relies on the principles of physics, such as center of mass and equilibrium, to create the optical illusion.
Fidget spinners spin due to the conservation of angular momentum. When you flick the spinner, you give it angular momentum, which is then conserved as the spinner spins. The physics behind this involves the distribution of mass in the spinner and the friction in the bearings, which allows the spinner to keep spinning for a longer time.

Native Americans and west African tribes used the rain stick
Yes stick instects do live in the rain forest. I live near the rain forest at Mount Tambourine, Australia and regularly see stick insects.
they made the rain stick by putting beans in a hollow tube and closing off both ends.
Oh honey, it's not like there's a VIP club for rain stick players. But if you must know, Carlos Santana is known for his magical touch on the rain stick during his performances. So there you have it, Santana is the rockstar who's made the rain stick sing.
the rain stick was first used in Chile and is a beautifut percussion instrument.
The area behind a mountain with little rain is called a rain shadow.
