we’ve seen the “ice water challenge” fail videos before but few rival the discomfort this one brings me, every single time i watch it. the noise of impact is absolutely fucking horrifying — there’s another one where a tub falls on a woman a small girl but it was a much smaller container than this.

i will be using the 2008 lexus gx470 (in the garage at the end of the vine) as a unit of measurement. the height of one is 6’ 2.6” from the bottom of the wheel (estimated in the photo) to the top of the roof.

there are roughly 1.5 gx470’s from the top of the football helmet to the top of the guard rail on the stairs. this equals about 9’ 3.5”

now, part of this is going to be guessing how much water is in that drum to begin with. a standard amount for drums that size is 32 gallons, although 44 and 55+ gallon ones are quite common too. let’s just assume it was around 40 gallons.

we can see in this screenshot (again, crude, was probably not a consistent water level all the way through the can, but) we can eyeball that it’s close to 1/3 full at this frame. (yes, i know my math is fucking laughable)

1/3rd of 40 gallons is 13.3 gallons of water. one gallon of water weighs 8.3 pounds. 13.3 gallons of water weighs 106.4 pounds. lets add 3 or 4 pounds (because the empty garbage can weighs a little too) and round it off to a cool 110 lbs.

using this handy tool we can calculate impact velocity and joules. velocity is 7.5m/second, and kinetic energy right before impact was 1413.1 joules, but this is not force of impact.

using that tool, we can calculate that after 0.1 meters of distance after impact, the average impact velocity is 14131.3 joules.

here comes the trickiest part. how much force does it take to break the neck of an average human being? a quick google brings up this:

The amount of force needed to break a neck bone is different from person to person. It also depends on the position of the head and neck when the injury happens. For example, when the neck is slightly bent, it is much more vulnerable to injury.

from all the other articles i found, a general consensus is that it doesn’t take much to break the neck. it obviously depends on many factors, and i doubt the football helmet helped him in any way. in fact, i’m sure that football helmet was preforming some leverage action and cranked that shit out even harder than it would have been without one.

however, in boxing, a 5000 joule punch (common hook impact velocity) is enough to spin the head at 43,000 RPM, which is very very likely to knock out a normal person — as in, someone who isn’t a well-trained boxer who works out their neck muscles to prevent this sort of thing from happening.

this has been equated to the amount of force a bowling ball has when it hits you at about 20mph.

we are dealing with 14131.3 joules, almost 3 times that amount.

9000 joules is roughly equal to 1 metric ton of force

3300 joules is enough to break ribs

2200 joules causes concussions and possible brain injury

it is very hard to find any reputable sources on how many newtons or joules it takes to break the neck due to the aforementioned reasons. in fact, most of my findings are complete and total estimates. please take this post with a grain of salt.

but i’m assuming this guy isn’t doing too well. poor dude.
