    I once bought a good boomerang, reach the instructions and followed them. On about the third or fourth throw I stood in amazement as the boomerang soared upward and arced around as it did what a boomerang should do. I didn't really believe that it was happening, I kept my gaze fixed on the flying boomerang right until until a sharp pain to my left-hand side roused me out of my trance like state.

  • @BBCEarthScience
    @BBCEarthScience  11 ปีที่แล้ว +25

    Well spotted! Small error in the Gfx. Each wing of the boomerang is bent at 60-80 degrees from a dead-straight stick, so one tip is actually 100-120 degrees away from the other tip. Eagle eyed Head Squeeze subscribers don't miss a thing!

    I don't understand how an obtuse angle can be less than 90 degrees? The angle between the wings of the boomerang is shown to lie between 60-80 degrees. How can this be possible, the angle is obtuse.

    Probably "throwing stick" (in Egyptian), which is what most australian aborigines called theirs (in their respective languages). There were boxes full of boomerangs in Tutankhamun's tomb, for example, and there are a few pictures showing them being used to hunt birds.

  • @NightEye87
    @NightEye87 11 ปีที่แล้ว

    The figure had both arms on top of each other. If you then rotate it (CW/CCW does not matter at all), it's over 90 degrees. If in the picture the arms were - as you say - in an angle of 180 degrees; then you would be correct.

  • @ian-c.01
    @ian-c.01 11 ปีที่แล้ว +1

    I believe they used kangaroo tendon for spears because it's easily shaped and can be over 2 meters long, not much use as a bow though.
    To my mind, the boomerang is the most unlikely weapon to be developed because it's very difficult to make using stone tools, difficult to use if it's not made really well and has limited uses unless you are very highly skilled at every aspect of their design and construction. It's not something that comes about by a string of accidents and then catches on.

  • @0YouCanCallMeAl0
    @0YouCanCallMeAl0 9 ปีที่แล้ว +5

    I'd like to see that 6 minute flight, seems impossible without some external lift - thermal, or ridge or similar. Even still it'd have to keep that rotation energy going for so long. Mind boggling.

    • @ozboomer_au
      @ozboomer_au 5 ปีที่แล้ว +4

      To get such a flight, you need to use a specific type of boomerang, that looks very much an ice hockey stick, is very thin and stiff and is very light. The lift differential between the short and long arms is such that when you throw the boomerang, it immediately gains great height (think 50m or more) and then flattens out so it hovers, much like a sycamore seed or helicopter blades. It simply takes a long time to come down that way.. and often gets a height push from thermals etc before it finally reaches the ground. I've been throwing and making boomerangs for 50+ years, and I held the Australian Maximum Time Aloft (MTA) record for 10+ years...

    • @fangsabre
      @fangsabre 3 ปีที่แล้ว +1

      Well, the thing they neglect to mention in this video is that the boomerang does actually achieve lift. They're designed to be wind foils, curved on top flat on bottom, to create negative pressure generating lift like the wings of a plane. So not only does the spin help it fly, but the air foil effect causes it to fly a surprisingly long time

  • @mrnickbig1
    @mrnickbig1 3 ปีที่แล้ว +1

    Wow, May was GROSSLY incorrect, especially with regards to the gyroscopic effect. Gyroscopic effect only provides a bit of STABILITY to help keep the wings aligned. The trajectory of the boomerang (why it comes back) is due to the DIFFERENCE IN LIFT generated by the advancing blade and receding blade. The blade rotating forward has more wind flowing over it, generating more lift, than the blade rotating backward. As the forward speed is reduced by drag, the boomerang will tend to flatten out with repect to the gropund, and make close to a vertical landing. Hunting boomerangs (kylies) have symetrical airfoils that don't generate significant lift, therefore they fly straight, no matter how fast they spin. DUH!

    Once me, my brother, and fiew of my friends were playing around with boomerangs, one of my friends Keven (not the real name) threw the boomerang and it went soaring. The boomering the turned around, came back, and hit him in the forhead. He was crying while i was dieing (id bet my bottom dollar that i spelled that wrong) of laughter. After appologiseing, and makeing shure Kevin didnt need medical treatment, we contenued playing with the boomerangs after getting bike healmets.

  • @Peepsydinks
    @Peepsydinks 11 ปีที่แล้ว

    It is not over 90 degrees, degrees is measured clockwise, meaning that while it is flat, that is considered a 180 degree angle, if you were to raise the left side up a bit that is 5, 10, 15 etc degrees. For it to be over 90 degrees it would have to bend more to the right, not left.

  • @RFC3514
    @RFC3514 11 ปีที่แล้ว

    You might as well say that it's illogical anyone would develop bows and arrows since slings work fine.
    Anyway, they did make some spears and bows, but both of those need long pieces of elastic hardwood, which weren't exactly common in Australia or Egypt (the earliest known boomerangs were made of ivory, BTW).
    Short bows aren't very accurate, and boomerangs are quite efficient for hunting emus (aim at the neck and you can miss by almost half the boomerang's width and still get a hit).

  • @ElNeroDiablo
    @ElNeroDiablo 11 ปีที่แล้ว

    It's 60-80 degrees from a dead-straight stick (so one tip is 100-120 degrees away from the other tip), not 60-80 degrees bend BETWEEN the tips.
    So if you got 3 boomerangs with a 60 degree angle (120 from tip to tip) then attached them so one wing of each overlapped with a wing of another, you'd get effectively a 3-blade propeller (which is 120 degrees gap between each blade).

  • @reNINTENDO

    Many inaccuracies in this one.
    0:42 - carpathian mountains are about 1600 km northwest from the place where they are drawn.
    1:03 - that's not 60-80 degrees. 120-160 is more like it.
    1:40 - this image is all wrong. What's turning is not the boomerang (it's turning all the time) but ist rotational axis which is perpendicular to the boomerang as it's drawn there. So the boomerang turns from "/" to "-" and then to "\" ... roughly, seen through eyes of the one who threw it.

  • @RFC3514
    @RFC3514 11 ปีที่แล้ว

    They didn't. They developed something curved to hit enemies around shields (combat boomerangs). But they also hunted with them, and that meant sometimes they needed to be thrown (ex., to knock down a bird). Eventually you start to figure out that some designs are more accurate than others (which led to hunting boomerangs, that fly very straight), and some curve in predictable ways (which led to returning boomerangs, that are mainly a toy, and sometimes used to scare animals towards the hunter).

    Yes I can accept that as a theory, I never considered their use as a weapon of that type, kind of makes a bit of sense anyway. Whenever I have seen images of aboriginals etc they always seem to carry the bare minimum of weapons that can double as tools.
    However I am still a long way from imagining that they would spend much time developing something like a flying boomerang when spears and arrows would easily kill prey from long distances. It just seems illogical to me.

    Not all boomerangs are meant to come back. Some aren't even meant to be thrown. It's not hard to imagine that they started out as combat boomerangs (basically curved clubs), evolved into hunting boomerangs (which are just thrown and don't return), and then someone noticed that a certain type of curve made them return.
    Unless, of course, it was aliens.

    Basketball is a much more modern invention and balls do not require very much trial and error to get right. I still find it hard to understand how they could have developed something curved for throwing, have you ever tried throwing a curved stick accurately ? A flat club is near impossible throw with any force and is certainly not ideal as a weapon. I think there is too much speculation in the history of boomerangs, I am very curious to find out how they were developed by ancient people..
