Lighting one sparkler = lame. Lighting 10,000 sparklers at the same time = an incredibly awesome idea that's just as epic as your kid brain always imagined it would be. 

This is just the sort of thing that your mom would have strictly forbidden you from even thinking about doing as a kid. Thankfully, somebody on the internet had the bright  -- pun VERY intended -- idea to spend too much money on 10,000 sparklers to create an incredible tower of flame.
