Zombie killing 101 - Unique Methods for Re-deading the Undead!

Good morning class! today were going to discuss the most obscure ways in which to re-dead the undead. now as we all know there are countless and imaginative ways to dispatch the undead. you can shoot them in the head, the bash their skulls in, you can cut off their heads, set them on fire, dose them with acid and far to many others to get into. Now what i want to discuss are what are some of the more obscure ways deal with our friends the zombies. as an example i would like to introduce you to a little known method called the BEAR TRAP GUILLOTINE!

This wonderfully underused method uses a large bear trap attached to a long chain to form something akin to the grabber in an arcade claw game. The survivor would then stand leaning the top half of his body out the second or higher story window of a building. the zombie would be down bellow, preferably right under the window, perhaps loured to the spot my the survivors call. the survivor would then lower the trap out the window by the chain. stopping just a hairs breath away from the top of the zombies head. the survivor would then line up the trap very carefully and then let the trap land dead square (pardon the pun) on the zombies head. this would trigger the pressure plate and the trap would close. given the rotting nature zombies in general and the amazing pressure the bear trap can apply when snapping shut. the trap would close breaking the zombies neck and in many cases removing the head altogether. the now headless body will fall to the ground and the survivor is free to pull the trap, along with the severed head back up to be dispatched with so that the rig can be reset. now while the bear trap guillotine is inventive and simple their is a reason it is not seen very often. one it requires the use of a bear trap, a hard to come-by specialty item. two it requires the survivor to be held up in a fortified two story or higher building. three the zombies need to come to the survivor. four it requires spot on aiming to archive which can result in a lot of failed attempts. five since the head of a zombie remains alive after decapitation this is not a one shot kill method requiring a second blow which places the survivor in risk of infection. how ever if the required criteria are met then this can be a simple and affective means of dispatching zombies trying to get into to your safe house.   

Well now its time students for you to tell me your most on Orthodox methods for re-deadtification. please be sure to explain it in detail and list its pros and cons and as always remember this will be on the midterm!
