Old pictures resurfaced!

Hello!

Work is still ongoing for the last beer can tower videos, the first of which will be the fast-motion of us building the final tower. The build constitutes 105 minutes of continual video, so it's quite CPU intensive getting it sped up and all put together. This is especially true as it was filmed with a pretty top-of-the-range camera, with the raw footage taking up 12GB in total. I've had to resort to using a proper desktop computer as my laptop couldn't begin to handle files that big!

The other videos are on hold whilst I gather all the footage together - different angles were filmed on many of my housemate's devices and I need to get a hold of all that before I start. These include the destruction of 19 and 20, but there may be others such as outtakes and a compilation of all the destructions in one video.

In the mean-time, here's an ancient photo which Dave recently stumbled upon on his computer. It pre-dates any of those posted when this blog began, showing the tower back when it was only 6 storeys high. I can't believe we even thought it was photo-worthy at this point, but here it is anyway!:

56 cans - only 1494 away from where we ended up!

 

Managing the Tower (Part 2)

Part 2: Construction

After collecting cans you're going to want to start building some towers! But how big a tower can you build with the cans that you have available? What shape should you go for? 

We opted for a triangular based pyramid as it proved far more stable than the square base. To work out how many cans you need boils down to just adding up some triangle numbers (or, alternatively, knowing your tetrahedral numbers!). Of course with a spreadsheet this becomes very easy, and it also helps with keeping a count of the cans as the number you collect grows beyond a reasonable size (you wouldn't want to have to count 1000 odd cans from scratch to check if there were enough!)

So once you've got the cans and you know exactly what you'll be building you can move onto actually building it. If you have cans of different sizes like us then you'll need to be careful with how you distribute them - obviously you need to keep cans of the same height on the same layer or your tower is not going to stand! Here's how we go about planning each construction... and surprise surprise, it involves the spreadsheet again!:

 

The numbers in bold at the bottom are triangle numbers representing how many cans should be on each layer. The number just above is a sum of the cans you've put into that layer so far so its easy to see if you've overshot it or need to add more. As you fill in cans in the middle we made it so that the number gets subtracted from the leftmost column and added to the rightmost. This example is for a 13 storey tower and so the total needs to reach 455 (bottom right). The rows marked in a pale red are the 500ml cans, which are distinguished from the others due to the difference in height.

Whether you decide to plan yours like us or just go for it, now all you need is a place to build it! Try to find a place that's flat and has room for the tower to grow. You want there to be as much ceiling space as possible (ours is around 3m high), and you also don't want it to be a place where people are likely to knock the tower down by accident! 

As the tower gets larger it will also get more unstable, and so if your floor isn't perfectly even you might want to make some kind of makeshift base to make things easier. We got 3 large pieces of card from Hobbycraft to make ours:

You'll need a steady hand (and, later on, quite a bit of patience) to build a beer can pyramid since once empty the cans are extremely light. Building beyond 14 storeys or so you may also need a chair or stepladder in order to place the top few layers! 

Once it's built that concludes the second step, and you can sit back and admire your work as you drink more cans in order to build something even bigger!

Managing the Tower (Part 1)

This post will be the first of many behind-the-scenes peeks at what goes into managing our beer can tower project. In part it will be a way of conveying the amount of hidden effort involved, but it should also serve as a pretty thorough guide should anyone reading want to create a tower of their own! And so here's the first (and potentially most enjoyable) part of the process - consumption!

Part 1: Consumption

You can't build a beer can tower without first drinking vast quantities of beer! This can be achieved a little at a time, or with the occasional mass-contribution through a night of drinking games (we recommend Beer Pong!). However you do it, you'll soon start stocking up empty cans.

Surprisingly that's not the end of the consumption step, though. All of these cans must then be de-ringpulled and, ideally, rinsed out. This can be pretty time-consuming, especially when 20 or more cans build up by the sink! 

Once washed and de-ringpulled, you'll need to find a way to store the cans in between towers. As the number of cans grows, so too must the number of boxes. Between our second and third year we found ourselves filling 10 IKEA boxes (see this post).

Finally, it's useful to have a system in place for logging how many cans have been consumed. For this we use a spreadsheet, which not only allows you to keep track of the number of cans but also other statistics such as total ml/units consumed and who they were consumed by!

With this final piece in place it becomes possible to tell exactly when there are enough cans to build the next size of pyramid, which leads to the next stage - construction!

Looking back: The Ocado Shop

The start of Term 2 brought with it an incredible stroke of luck which led to our most outrageous bulk order of beer to date. Supplies of beer in our house were running low, and whilst we wanted to order more online none of the standard supermarkets seemed to be offering any deals.

This all changed, though, when we received an Ocado gift voucher from WHSmiths and decided to check it out. In so doing, we stumbled upon a mistake on their website where they were offering £12 15-packs of Carlsberg on 2-for-£10.

Needless to say we capitalised and ordered 14 boxes (210 cans-worth), which combined with our £10-off voucher cost us a grand total of £60. That works out as £2 for every 7 cans of beer!

When we checked back on their website the next day we discovered that the pricing had already been corrected to 2-for-£20. Not that it mattered to us though - we'd already bought 92 litres from them!

Cheers, Ocado!

Looking back: Year 2 Term 1

With the summer behind us we found ourselves moving into our new house in Coventry and beginning our second year. It took us some time to get the cans out of storage (read: back from Jon's grandparents!), and the cans drunk during this period combined with the small number we collected over the summer meant that by the time we got the first year cans back we had enough for 11 storeys.

Things were not all plain sailing though. The carpet in the new house was particularly uneven, which ultimately led to us buying some big sheets of thick card to form a base. Finally, on the 6th of October 2011 the beer can tower was reconstructed in its new home.

BCT9 - 165 cans

BCT11 - 286 cans

BCT10 - 220 cans

After this the cans came flying in - we had 237 cans in total during this term which beat our entire first year of university. By the christmas holidays the tower was comprised of 13 storeys and was an impressive 2.16 metres in height. Its construction marked the first time we had needed a chair in order to complete it, which was an achievement in itself! We also experimented with a beer can 'castle', comprised of a 10 storey tower with two 7 storey towers attached.

BCT12 - 364 cans

BCT13 - 455 cans

Castle - 388 cans

Sometime during this term it became clear that our original 15 storey target was going to be smashed. We also realised that the tower's new home could only last for one more storey before it extended out too far into the corridoor, and so it was going to need to be moved elsewhere...

Looking back: Year One

Our first year of university was where it all started. It was in October 2010 that we all arrived at Warwick University, although the tower itself did not begin until mid-way through our second term.

The earliest record that I have of it comes from the 28th of April, 2011. By this time the tower was already at 7 storeys, although in actual fact this only represents 84 cans. The tower continued to grow slowly during this time, until we eventually reached what would be our peak of 9 storeys sometime in June.

This isn't quite the full story though. Not long after building the 9 storey tower, I returned to my room one evening to find it scattered all over the floor - I can only assume that it fell victim to a vaccume cleaner one morning. In fact by the end of our first year we had enough cans to build a slightly more impressive 10 storeys, but with the tower in pieces we decided to leave the construction as something to look forward to at the start of our second year.

Cleaner Strikes!

At the end of a rather uneventful first year, then, we boxed and bagged up 233 beer cans, ready to recommence construction when we returned to uni the following October. Back then I remember us deciding that 15 storeys would be a respectable target for the end of university - however as I'm writing this we are nearing the end of our second year and have already constructed one better than this!
