So, over the weekend, I did a little science experiment. Maybe it shows validity to the WTC7 FFA, maybe it doesn’t…but it was fun to do none-the-less.
Materials:
- 3 standard bricks, like you see in a walkway.
- 8 plastic drinking straws (the fatter ones, like you get at BK) each cut in half to make a total of 16.
- A handful of wood matches.
- Some masking tape.
- Some type of putty, like playdoh.
First prepare your straws. On half of them, tape a match to them so that the head in near the top of one side.
Brick #1 goes down first. I used a little clay to set 8 straws in a pattern of 4x2. Each of these 8 straws are the ones that had a match taped to them with the match head pointing down. Throw a bunch of the matches in a pile in the middle and then, carefully, place Brick #2 on your straw columns.
Repeat this process (minus the pile of matches) and, even more-so carefully, place Brick #3 on this concoction.
Now the fun part … light the pile of matches.
My findings: As soon as those interior straw columns began to melt, the entire structure fell. Once the first floor collapsed, the top brick crushed the straws on the second floor with little effort and/or resistance.
Is this real life? No, I’m not pretending it is. But it
does show that it only takes for a weakened foundation to bring down a whole building without batting an eyelash. And it does give a basic insight to how WTC7 fell so easily after burning uncontrollably for 7 hours.
I’m trying to find a way to make this project a little more realistic in its materials, but I've got some math to do. I’ll also probably film it next time so I can share what it looks like.
... the life of a science nerd with nothing better to do on a Saturday afternoon …
