Matt sent me this wonderful article from Danâ€™s Data on how to build a Sparkler Bomb. It is the perfect at home project for anyone looking to blow something up in a dangerous and awesome way.
From the site:
Here you will learn the essentials of making an improvised firework which, while spectacular, is also both as predictable and as safe as something that blasts a mighty shower of sparks 50 feet into the air can reasonably be expected to be. I have made many of these things. I have been quite close to them when they went off. I have never so much as lost any hair, which is more than I can say about the results of some of my other half-baked pyrotechnic experiments.
And here is the description of the event:
Now the standard sparkler bomb ignition sequence will occur:
1. The fuse will burn right down to the level of the sparklers.
2. Some turkey will say “Itâ€™s not going to go off!”
3. After a short delay determined by how well you packed the sparklers, it will go off, and a large number of sparklers that would each burn for a couple of minutes will be consumed by the very fires of Hell in about one and a half seconds.
4. One and a half seconds later, the crowd will emit various whoops and whistles.
