It was a big summer for Harry Potter. The seventh and final book in the series, Harry Potter and the Deathly Hallows was released, as was the fifth movie, Harry Potter and the Order of the Phoenix. After reading the first and seeing the second, I was reminded of a hoax I've had sitting on my hard drive for a few years, just waiting to be debunked.

Can a prescooler get drunk and even die from drinking hand sanitizer? The short answer is ... yes, they can. The following e-mail describes swallowing a squirt of hand sanitizer was enough to make a four-year-old loopy and while it gets some of the specifics wrong -- namely that the child couldn't have had an 85% blood alcohol level, since .10% is enough to kill you, and she probably had a lot more than one quirt -- the general warning is valid. Most hand sanitizer contains a large percentage ethyl alcohol, which can be intoxicating and even deadly if swallowed.

An e-mail claims that Mars will soon be looming so large in our skies that it will rival the moon. The truth is that while Mars did get very close to Earth a few years ago, that merely turned it into a slightly brighter red star in the sky. If it actually did get as close as the email claims, the Earth would be wracked by high tides and thrown out of its orbit.

An old virus hoax stumbles back to virtual life with a debunking bait-and-switch that points to a real threat, then repeats the same tired warning.

Thinking of getting one of those magnets or additives to increase your fuel mileage? Keeping your car windows rolled up to reduce drag and save gas? Letting your car idle so that you don't use more gas by restarting it? Think again -- CNN explains that these and other folk remedies simply don't work.

Given the history of spider urban legends, this is sure to mutate into its own horrifying story in about, oh, 20 minutes. According to this Associated Press story (which includes a photo of the kid holding up a jar with the drowned spiders in it and quotes from the doctor involved), 9-year-old Jesse Courtney of Albany, Oregon complained of hearing crackling and popping noises in his ear. When the doctor flushed his ear out, two spiders -- one of them still alive -- came tumbling out. There's no explanation in the story of how the spiders got there in the first place, but don't worry -- I'm sure some hoaxer out there is whipping up one as I write this.

Ah, Bill Clinton. I'd almost forgotten about all the great hoaxes, urban legends and miscellaneous crap that was circulating the Internet back in the heady days of the Dot Boom. Now that his wife is looking to make a presidential run, it's all floating back to the surface, as is illustrated by the email alleging that Bill Clinton is the first pardoned felon ever to server as the president of the United States. It's alleged that he broke the law by dodging the draft, and then was pardoned as part of Jimmy Carter's blanket draft-dodging pardon in 1977.

Snopes.com has an excellent debunking of this e-mail, pointing out that while he may have used political favors and broken promises to avoid the draft, Bill Clinton never officially broke the law.
