Video: Igniting 10,000 sparklers at once was a cute way to ring in the new year, but assembling 100,000 sparklers into a tower and adding fire is probably as close as one could get to building an artificial working volcano.
The usual 'don't try this at home' disclaimer comes into play here, but the cost of burning 100,000 sparklers -- easily a lifetime supply for some people -- is prohibitive enough. Besides, it's now officially already been done. If you want to impress the internet with another sparkler experiment, you'll need to up the count to a million. Well? We're waiting.
