The History and Mechanics of Boomerangs
TLDR Boomerangs, perfected by aborigines in Australia, come in two main categories: ones that return to the thrower and ones that are used for hunting but do not return. They work on the principle of lift, spin, and gyroscopic precession, and require careful crafting and throwing techniques.
Timestamped Summary
00:00
Boomerangs were perfected by aborigines in Australia and there are two main categories: ones that return to you and ones that are used to kill animals but do not return.
03:48
Boomerangs evolved from early tools and were perfected by aborigines in Australia, with two main categories: ones that return and ones that are used for hunting but do not return.
07:31
Returning boomerangs are lighter and more aerodynamic, with a design that includes two-pronged propellers that rotate and lean to the left, allowing them to come back to the thrower.
11:35
Boomerangs work on the principle of lift, similar to airplane wings, and have an invisible axis of rotation that allows them to spin and move forward simultaneously.
15:37
Boomerangs create torque and gyroscopic precession, which allows them to spin, curve, and return to the thrower at high speeds.
19:31
Boomerangs need to be handcrafted, thrown, and tweaked until they are adjusted just right, and wind can play a role in how they move.
23:30
To throw a boomerang, you need to angle yourself against the wind and throw it at a specific angle, keeping in mind that it can be dangerous and you should always keep your eye on it.
27:01
To throw a boomerang, you need to snap your wrist, throw it at a slight angle, and clap your hands together to catch it; boomerangs spin on six different axes when thrown.
