    OK, not quite...<br><br>...but some nice firecrackers!<br><br>Type II explosives, legal to fire in Germany only from the 31st of December until the 1st of January. <br><br>I made myself a slingshot for these nice crackers three years ago, but this year it has to be a launcher. <br><br>So I made a typical in-liner, chambered for the largest legal firecrackers you can buy here (23 mm diameter, filled with black powder). <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/baller10.jpg" border="0" alt=""><br><br>The firecrackers are loaded into the breech, winchester style.<br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/baller11.jpg" border="0" alt=""><br><br><br>The built-in strom lighter helps keeping things under control, under time pressure. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/baller12.jpg" border="0" alt=""><br><br>It works fine! <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/baller13.jpg" border="0" alt=""><br><br>Will increase the rubber some and also put in a steel piece to protect the wood from the burning fuse. Will do a video on the 31st!

    <span class="postbody"><br><br>... or just put fireproof material over the fuse to make it windproof also. cause i don't know at that speed it's flying if the fuse gets out or will burn rapidely by getting lot's of oxygen.</span>

    The fuses on those firecrackers look very short, how much time do you have before they explode?<br><br>Could they be shot into gel? <img src="http://illiweb.com/fa/i/smiles/icon_bounce.gif" alt="bounce" longdesc="27"><br><br>Maybe they could be launched from a device that once shot a spear? <img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28">

    <span class="postbody"><br><br>The fuse is longer than it looks, the first centimeter of the firecracker is hollow. These babies burn about seven seconds before they explose, plenty of time. I actually have to count to three before I fire, or else they explode too late. <br><br>I have actually prepared a nice 10 kilogram block of gelatin. I think the sticks will go in. I always wanted to see what happens when a firecracker goes off on the middle of a gel block...<br><br>I may have to add a false tip in order to protect the burning fuse, though. <br><br><br></span>

    Here is a picture of the finished weapon. More rubber, stirrup (made from an old aluminum pipe) and a front handle. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/baller14.jpg" border="0" alt="">

    <div>I used to shoot Black Cats from my sling. I would put them in the pouch, draw back and light them with my cigar, pull back a little more and FIRE! <img src="http://illiweb.com/fa/i/smiles/icon_pirat.png" alt="pirat" longdesc="23">

    <br>Failed perception is when you have a gun, I have a slingshot and you think you are the only one that is armed. <img src="http://illiweb.com/fa/i/smiles/icon_lol.gif" alt="Laughing" longdesc="7">

    I cant wait to see this video, to many stupid people blowing their fingers off were i live, ever thing is illegal year round, it is nice that Germany lets you set them off at least a little bit.<br><br>Which way do you plan on orienting the fire cracker, so the fuse is facing forward or backwards? (i cant tell from the pics) <br><br>Also it would be cool if you could build a barbed point, so you could shoot it in to something and know that the firecracker wont bounce off. just an idea.<br>

    Very fascinating contraption! <br><br> I like the fact that this shooter shows how thin the line between recreational and overall fun stuff and real-deal weapon. Don't want to give anybody any bad ideas, but seal the the same black powder in a tublar metal projectile of the same size (perhaps with a spike on the front), wrap needles around the tube with some ductape...and voila, you have a crude, but really nasty mini-grenade and a suitable launcher that can toss this "munition" quite far. Made out of materials that always will be available for everybody around the world.<br><br> Again, don't want to encourage anybody to make something like that (most likely it would be not only illegal, but also quite dangerous!), but it is really astonishing how much can be done without any expensive power tools, complex metalwork and other stuff like that! Well done, Joerg, well done - as usual <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><br>
