Metal Ninja Star





Introduction: Metal Ninja Star

This Instructable will show you how to make a very simple ninja star with something everyone probably has in their house and you can also make chili with it!!!!(dont throw this at anyone it can really hurt someone,i got my to peirce 3 inchs of drywall.)this pic isnt the real nija star you will be building srry.

Step 1: Gather Materials

To make the ninja star you will need:

-One large tomatoejuicecan(works the best)
-A can opener with the pointy thing as in the picture.

Step 2: Step 2

Step2:Make 2cuts with the pointy part of the bottle opener across from eachother like shown in the picture.I didnt have any tomatoejuice so I used a tuna can but the large tomatoe juice can works the best. You will have alot of trouble making it if you don't have a tomatoe juice can.

Step 3: Step3

Now do the same thing just turn the can and make 2 more cuts across from eachother as shown in the picture.

Step 4: Step 4

Now cut between all the other cuts evenly as shown in the picture.

Step 5: Step 5

For this step cut on the 8 flaps and then it should have sharp points on it,do this on the next 7 flaps and it should fall to the bottom of the can but if one of the points is still stuck to the can take pilers and twist it off...................then find a flat surface that is hard like your garage cement and then take a rubber malet or your feet and flaten the points so they are level and your done.Srry there are no pics for becuase my camera ranout of batteries. Try making 2 ninja stars and then hotgluing them together for a stronger impact or something like that.

    hey idead could i add for fun a small static charger to the metal so in thery i would have a nija star knock down strike evry time

    I wouldn't suggest hammering it out on the cement... it chips too easily. I would suggest some sort of strong metal sheet, or an anvil.

    if u use a rubber mallet it wont chip the concert or whatever it rubber

    i had an old cassette tape eraser that had metal that held in the magnets and i made a real one. now i can say i made my shaken out of a cassette tape eraser.

    Their response: "You made THAT out of WHAT!!!!!!!"

    Cool, this is much more reliable than some of the other sites i've visited.

    looks just like my real one

    that is one awsome shuriken


    stop calling them "ninja stars"
    i know because i have my own
    this is a proper shruiken

    man, I was wondering if anyone else had thought of this.
