While this really should be a story for A Good Toilet Paper Blog or maybe a Becks Booster Blog, it is interesting to note the reference to beer in this story:

I would like to point out that there was no beer involved in this matter. The can is clearly empty. As this story shows, the can involved was a leftover after being drained of its macro gak with residual local legacy branding: Keith's NIPA. Sibling brand to other expressly confused brews, Keith's Not IPA is a premium brand that costs a lot and offers not all that much usually... but in this setting at the facility formerly known as the Skydome in Toronto one that might have actually cost the drinker over ten bucks. Accordingly, it was not likely containing any beer when launched. The video seems to confirm this lack of weight. Which means it had all the violent menace of the happily bouncing toilet rolls and that it was not an oblique reference to the brewing industry but the canning and packaging industry.

So, get the story straight. It is not a can of beer when the beer is long gone. It's just a can. So shame on the profession of canning engineers and designers of canning for making an object that when emptied is almost aerodynamic. Shame.
