At-Home Engineering Challenge #4

Week 4 already? Yikes. Well, here’s helping you not run out of activities.
After this week, we will have 1 more competition (participation here and at work has dwindled).
Remember, the person with the most points at the end will receive a $50 Amazon gift card.

Challenge 4 - Paper Tower
Using no more than 20 sheets of 8.5" x 11" copy paper
And no more than 20 of the following fasteners: staples, paper clips, binder clips
And string, twine, or 550 cord of a reasonable amount

Construct the tallest tower that holds a (full) 12 oz can (soda or similar - should weigh at least 385 grams).

-Height is the vertical span from the surface the tower rests on to the top of the soda can
-The top of the soda can must be the highest point of the tower (no suspending the can).
-Tower must be free standing, and may not lean against anything (e.g. walls) for additional support.

-Competition runs through 5pm Eastern on Sunday.
-Please respond to this post with your solution, include a picture of your build (with measuring tape or ruler verifying measurement)
-Only one entry per person, 1st submission will be used. No post edits or deletions.
-All decisions final, don’t like my rules, run your own competition.


2 points for participating in this challenge
2 points for additional pictures of your deconstructed tower, making easy to verify you followed the rules
3 points for constructing a tower taller than 18 inches tall
3 points for constructing a tower only out of paper and taller than 15 inches tall

5 points for constructing the tallest tower
3 points for constructing the 2nd tallest tower
2 point for submitting before Friday.

Example materials:

More on the definition of “reasonable amount” of string… if you tower looks like it’s more string than paper, it probably isn’t a reasonable amount of string. :wink:

20 each or 20 total?


can each of the 8.5"x11" paper be broken/cutted up/divide into multiple sheets? i.e. 1 full size into 4 sub pieces or more?


Does before Friday mean by 11:59pm Thursday? Or by the end of Friday?

Friday would be too late.

For my submission, I decided to go with no fasteners
All rolls were 2 layers of paper
19 sheets used
0 fasteners

44 inches tall.

I layerd 2 sheets together, folded the edges for rigidity, and made folds on the end to complete the rolls

In between each roll was a single sheet of paper folded for extra strength.
Sorry about the bad picture quality, cracked the camera glass on my phone and haven’t replaced it yet.
11:59pm :wink: Thursday


If I were judging this i would give you extra points for using the best soda


Lol, I don’t drink any soda, that was just the only can I could find in the entire house :sweat_smile:


I was just going to say this, but I think that it would’ve been DANKER if he had used Baja Blast


Can we not summer cd in my engineering challenge topics? engineering challenge is serious business, $50 amazon gift card on the line


It’s called pop mister


20 sheets of paper
20 fasteners
Only 1 casualty of soda during testing. It will be remembered in the root beer float I am having as I write this.

Anyways. here are the pictures

sorry guess my computer dosen’t like a lot of photos at once. here you go

47 inches to 44?

JKBear 331 - 2 + 2 + 3 + 0 + 5 + 0 + 0 = 12
Sam_J4409 - 2 + 2 + 3 + 3 + 0 + 3 + 2 = 15
