michael created the topic: Homemade Binary Explosives (Tannerite)
I love the stuff! When used correctly, Tannerite explosives are incredibly fun, and incredibly dangerous. They also aren't cheap - unless you make your own.
Fortunately, the mixture isn't all that complex. In fact, it isn't complex by any stretch of the imagination. With some basic math, two ingredients, and some willpower - you can start making it yourself.
Ammonium nitrate in the bead form is fine - it isn't necessary for it to be powder. The aluminum oxide powder, however, must be a very fine powder. If you've got aluminum powder that's more course than dust (if you can identify individual granules without a microscope), then it isn't fine enough - stick it in a blender or coffee grinder until you reach the necessary consistency.
A word of caution - if you find it necessary to grind/blend both the ammonium nitrate AND the aluminum oxide - DO NOT BLEND IN THE SAME CONTAINER. The blender has enough energy to start the reaction. If you only have one container to blend in, WASH IT before blending the second component.
When transporting, keep in separate containers until you're ready to blow it up. This is for both legal and safety reasons.
So, the all important ratio is....wait for it...19:1
Yeah, unimpressive. Something so cool should be more complex...I know. 19 parts ammonium nitrate, to one part aluminum oxide. For those who think better in percentages, it's 95% ammonium nitrate to 5% aluminum oxide.
The recipe continues....mix it well.... Again, anticlimactic. For those who have never mixed store-bought tannerite - the mix is very important. If you're using the blackened aluminum oxide, it's easier to determine if your mix is good - it should evenly coat the ammonium nitrate beads (if you're using the beads) and you should have a very even medium gray with no variation. If you can still see white (or lighter gray) ammonium nitrate, then you're not done mixing.
The safest way to mix is to use a container leaving a little empty space. then rotate for several minutes in all directions, around the axis, end-over-end...I suppose you could shake it as long as you're not a super-hero.
That's it....measure, mix, and shoot
Now, a safety warning. For every pound of tannerite you mix - be no closer than 100 yards before you shoot it. So if you decide to mix a 5 pound batch, you need to be 500 yards away before you shoot at it. Even if there is no flying debris - the shockwave alone can kill you if you're too close.
