Introduction: Indoor Boomerang

Picture of Indoor Boomerang

I teach a class called "Make and Throw a Boomerang in One Hour." Actually you make three boomerangs in this class:

1. A light weight indoor boomerang to learn the basics.
2. A heavy cardboard one that flies outdoors in a light wind
3. A boomerang made from heavy polystyrene foam that flies in light to moderate breezes.

All three use the same template. This instructable is for the indoor model.

Step 1: Template

1. Download this template
2. Cut it out
3. Trace around it onto a piece of cardboard. Cereal boxes work well as does the poster board.

Step 2: Start Cutting

Ready to cut

Step 3: Cut, Cut, Cut

The card board can bend a bit as you cut as long as you don't overdo it and put a heavy crease in it.

Step 4: Camber the Leading Edge

Boomerangs use aerodynamic lift (among other things) to help it fly and return. This is a "right handed" boomerang, pinch and bend along the "leading wing" as shown below.

Step 5: Camber Trailing Wing

Pinch and bend the trailing wing.

Step 6: Tuning

This part can be tricky but typically both wings need to be bent up just a little bit

Step 7: Throwing

Throwing is just like a real boomerang.

Safety First:

1. Do not throw at anybody. Yes this is cardboard but NOT practicing dangerous behavior can be a useful process.
2. D0 not throw it like a frisbee. It tends to make a rapid ascent and and even more rapid descent in most instances with little predictability. Again not super dangerous with cardboard but . . .


1. The grip is a light clasping between the thumb and knuckle/first joint of the index finger.
2. The throw is like snapping a whip. You don't need to "twist your wrist" to make it come back.

Youtube helps as always:

These youtube videos are for outdoor but very good:

Several things maybe happening:

1. If you are left handed the airfoils are "opposite" of what they should be. Either make a new on "backwards" of try thowing right handed.
2. Throwing like a frisbee. Parallel with the ground will make it go way up sharply and back down sharply.
3. If it is "almost" coming back then you need to make minor adjustments on how close to perpendicular the boomerang is when you throw.

Look around on Youtube for "how to throw a boomerang" and you will find some good tips.

It is not easy to throw one and have it come back in even the best circumstances. There is considerable finesse involved in both making and throwing boomerangs.

Keep on trying though! Let me know how you are doing and I will see what I can do to help.

These work great! Thanks man!

MPLS_CBG (author)DANgerous1242011-08-03

Thanks! I have had some pretty amazing flights with these little dudes.

builderkidj (author)2011-06-16

what about corogated cardboard...?

MPLS_CBG (author)builderkidj2011-06-16

It might work with a slightly larger version. In general when I have tried to use corrugated cardboard it doesn't seem to hold the creases and bends that poster boards does.

Good luck!

why the pdf cannot be download

MPLS_CBG (author)forexjammer22011-05-21

you should be able to download the pdf template:

If not send me your email address and I will send it to you. If you want to download the complete pdf instructions you now have to be a "pro" member of Instructables. . .or something like that.

Good luck and keep me posted. I am here to help.

awesome boomerang. one tiny problem i have: it needs quite some force and space. can help me out?

MPLS_CBG (author)BraisedDuck2010-09-30

If you bend the wing tips up it should fly in a tighter circle.

libed24 (author)2010-08-04

how do I throw it?

MPLS_CBG (author)libed242010-08-05

Check out: Not quite as hard but that is kind of the idea.

aidoggy (author)2009-10-11

Ive found that throwing with your elbow instead of with your wrist or hand it works better.

MPLS_CBG (author)aidoggy2009-10-11

     I am glad you are enjoying the mini-rang.  The same pattern can be used on heavier cardboard and a sheet polystyrene material available at many hobby stores.  Cut it out and bevel the edges the same way, bend the wings for tuning the same way.

Except for two things

1. to bevel the polystyrene use a pair of pliers
2. to tune the polystyrene mini-rang the wings get bent down a little instead of up.

I will try to post some more instructions and pics soon but I don't have a camera and need to schedule in photo shoots with a friend.

aidoggy (author)MPLS_CBG2009-10-15

Thanks.I will be sure to try that

aidoggy (author)2009-10-11

I have tried this and thougt it waorks great considering how easy it was to make.Great instructable!

EncasedDeath (author)2009-10-04

works great, but mines kinda hard to catch.

venkboy (author)2009-10-03

Awesome! I tried it out right away, and it turned. I wasn't able to throw it with full force due to lack of space, just a very small flick (no I did not flick my wrist, just hand).

MPLS_CBG (author)venkboy2009-10-03

Bravo! I am so glad to see the instructions make enough sense for people to have some success. Many happy returns, Ed

smeagle (author)2009-09-30

This was AWESOME! iv'e managed to tweak mine to come back within one foot! Its awesome!

MPLS_CBG (author)smeagle2009-09-30

Glad you like it. I have one I made a few months ago and tweaked it again (the airfoils don't stay creased for ever) and it flies better than it did when it was new.

namdeo.d (author)2009-08-17

would it return??

MPLS_CBG (author)namdeo.d2009-08-18

They fly great. Indoors where there is no to very little wind. Not quite as well as the tri blade indoor in this video but pretty darn good.

Kiteman (author)2009-05-31

That template - what software is it (my computer hiccuped trying to open it).

MPLS_CBG (author)Kiteman2009-05-31

It is supposed to be a jpeg. Hmm. I will check it out
