I don't understand why 4 people voted for my tower

(I voted for TBD)

either respect for you, or disdain for me.

to you, too!

zoom at 6" (we had to lift the measuring tape slightly off the table because it caused the table to wobble.)

side view (once again, the tape measure was slightly lifted off the table)

post it support beam, shown to be 3"


Taking it down to count, shows only post it notes were used.


Pennies it held was.....................253 which comes out to 1.394 pounds. it could have held more, but we ran out of pennies.


This was a joint venture between me, freshgeardude and my brother, thescreensavers.

nicely done!

 

[YOyoYOhowsDAjello]

Sorry, I was out rock climbing.

Based on that 253 result and only being limited by the number of pennies, I've sent a PM to The Boston Dangler (the fearless leader of this week's challenge) to see if we should keep the challenge as is or alter it.

Seeing as the limit was the number of pennies your group had, freshgeardude, would you guys have any objections or opinions on making the requirements different so people would be less likely to run out of pennies?

Of course the decision is totally up to The Boston Dangler, but I think that it might be appropriate to make the height requirement higher, reduce the number of Post-Its, or both.

well I for one dont want a change.

we spent a lot of time on it and deserve the effort to be counted. If you do change it, ours should still count at 253.


the best deal is to not change it and just sit with it for this week.

Maybe I put the standards up high?

Ok, I got 477 pennies + 17 metal washers.

My gf thinks the metal washers are about equal to 10 pennies of mass each, so that's roughly 647 pennies worth of mass.

(Pictures and video to come)

Video

The key was to make the penny stack support itself - I put a piece of Post-It Note in every 10 pennies

My gf just found another of the fallen pennies - that makes 478 + the washers

the whole folding the post it notes into a triangle/circular came from us right? hehe It really holds alot of weight

When we were just building it I put 5 pounds on top of 4 it was holding till I put a book ontop of it and one of the legs failed lol.

Well the 6" lends itself to having two layers of supports that are 3" high each. That's what I was planning from the beginning.

I'm glad that 2 7/8" Post-Its are actually 3"
(They are, right? I'm not just bad at measuring?)

Slow motion collapse
(sorry about the terrible audio)

thats pretty cool, higher fps camera would of been awesome for the bottom when it just popped out lol.

oh and btw that watch looks a bit tight being serious, can you fit your index finger in between the band? if not its too small, your hand will shrivel up and die! lol

that sounded just like atari 2600 games!

 

[Safeway]

I read the instructions better this week. I shall be victorious.

 

[Freshgeardude]

if your putting washers, then it shouldnt count. if you want to count that, I can put a 5 pound book on mine

 

[The Boston Dangler]

after some careful consideration, the rules as stated remain intact. abrupt rules changes are for emergencies, and running out of pennies (in this context) is not an emegency.

It slides around on my wrist
Yes, I can fit a finger between the band and my wrist.

My point in putting the washers on was to find the maximum it could hold.

This was my first tower design and based on my results, I think it could probably hold 650+ pennies.

When your group had your hold 253 pennies, I already thought that we needed to change it as to not have people unable to participate due to running out of pennies.

Now that I suspect people are going to have to use $7.00 or more worth of pennies, I think it's ridiculous. This is really more of a "see how many pennies you can stack carefully" than a tower competition

 

[Freshgeardude]

I think its more of a how many pennies can you get type of challenge

 

[Tim]

I'm on the t-shirt design NOW.

Hmmm....

http://wiki.answers.com/Q/How_..._does_a_US_penny_weigh

I knew the composition of pennies has changed over the years, but I didn't know it was going to affect it that much (3.11 grams vs. 2.5 grams per penny).

Assuming an average of 2.8 grams per penny, that means that 162 pennies is about a pound?

So 477 pennies is about 3 pounds worth
647 is about 4 pounds worth

 

[DrPizza]

Wow, I missed this competition last week. Wish I had seen it though.

Now I have to see how many pennies I can find around the house.

I think you'll find that the majority of the pennies you had were the newer pennies @ 2.5 grams. I had already considered the jar of wheat pennies, but realized that would be handicapping myself by a pretty significant percentage!

Yeah, I'm at work without the pennies I used.

I was only able to scrounge 18 more pennies from around the office

Maybe it's time to make a trip to the bank

EDIT: I checked out the 18 pennies I have access to. 1/3 are the heavier ones.

 

[The Boston Dangler]

i'm not prepared to go through 5000 pennies to pick out the lightweight ones. not yet, anyway

[YOyoYOhowsDAjello]

Ok, I have another whole bunch of pennies now.

I'd have to estimate about 800-900 now total.

HomeBrewerDude wants to try a tower as well, so my plan is to bring the pennies to work today and let him take them home tonight.

If all goes well, he'll remember to bring them back to me Friday so that I can try one more tower over the weekend.
