5 Christmas Gifts for the Kids of the People You Hate the Most

This little toy car from the Disney movie 'Cars 2' features quotes from the movie that blare out at 124 decibels! That's as loud as the average rock concert and can cause instant hearing damage. It was rated as the loudest toy of 2011 by the Sight & Hearing Association.

I once heard someone describe glitter as the "herpes of the craft world" for it's incredible ability to spread. Once you introduce glitter into a house it will be everywhere and you'll never be able to clean it all up, it will haunt you forever! This 1 pound bag outta be enough to excite the kids into doing a craft project and cause a mess for years to come!

Kids love popcorn, so this next product on our list is sure to cause chaos with who ever you decide to unleash it on. This isn't just your ordinary popcorn, this stuff is infused with caffeine to keep the kids going all night, dump this popcorn in a decorative holiday tin bucket for stealth implementation. Use this in combination with another item on this list for maximum results!

With a product description like this, how can you go wrong? "Grow your own friendly germs and fuzzy molds. Mix up a batch of coagulating fake blood. Even make a stinky intestine. Learn the science behind unmentionable bodily functions while doing some truly NASTY experiments." I'm sure Mom and Dad will be fighting over who gets to help when little Timmy wants to do the "stinky intestine" experiment, have fun with that one!

Judging by the viral video of the kids destroying a house using a bag of flour, this has to make it on the list.  Getting the kids to actually play with the flour and making the parents disappear for a bit while the kids "play" is up to you, but this simple cooking product could cause headaches for hours or days if implemented correctly.
