This seems to simulate the pressure due to the weight of the bricks, but I wonder how much the height comes down by if you factor in the extra pressure you have to put on the top brick to get it to clip on. Does this add non-negligibly to the pressure on the bottom brick, or is it almost nothing once dispersed through the whole tower? (You may be able to tell that I have very little knowledge of the physical sciences…

If that's an issue, maybe you can add new bricks to the bottom.

You could just hold the second-to-last brick while you clip the last brick on it :)

Is anyone else excited by the fact that your average Lego brick can easily hold a human's weight? So if you built things out of LEGO you could, at least in theory, stand on them.

I stand on the #$%(@& things all the time and wish they'd just crush under my feet instead of being near-invincible by comparison with my soft cells. ;)

Anyone with kids is well aware of this fact - though they rarely intend to stand on them!

As a parent, I really, really, really wish they'd collapse under a human's weight. That shit hurts.

I'm a little confused. That's the weight that a single Lego brick can withstand, correct? So assuming you made a "tower" that was essentially a vertical line of 2x2 Lego bricks, it'd collapse after 3,591m. But that's not how we build towers. If you create a proper foundation with Lego bricks and distribute the weight evenly across them, and taper the tower as it goes up, am I wrong in assuming it could go a lot more…

Probably the proper translation out of geek-speak and into reality is that there is almost certainly no real structure that can be made purely out of Lego bricks that will cause the lower level to mechanically fail. (I'm hedging for safety. I really want to say there isn't one at all, but I've learned not to underestimate people's ingenuity. But let me point out by "real structure" I mean one that can be reasonably built in the real world, not, for example, a structure a mile high with millimeter tolerances made out of mass-manufactured plastic bricks.)

For another example, one could try to create an inverted pyramid on one brick to crush it, but it will topple long before it crushes the brick.

The structural strength under that circumstance (pure Lego, nothing else) is so enormously high, as determined by this experiment, that there's no reason to ever worry about this eventuality.
