0:02- primitive upward transfer method just wasn’t reliable enough to send dominoes all the way up to the top
0:08- no demolition system was built at the base of the pillars to allow falling planks to trigger their collapse
0:12- terrible trigger mechanisms were not sufficient to destroy the structure
0:21- tower did not have a proper pivot point that could make it hit directly in the center of the bridge
0:24- dominoes were spaced too far away from each other to be able to make such a steep turn
0:30- dominoes got stuck on the edge of the bridge
0:38- no demolition system was placed under the Octotower
0:40- rumbles caused the domino lines at the top to fall out of order
0:41- domino field placed too close to the next segment of the contraption, cutting off the domino sequence
0:45- improper pivot points under the bridge busters, towers didn’t weigh enough to cause meaningful damage
0:52- ran out of planks, couldn’t finish the contraption so we built some towers that weren’t enough to knock such short bridges
0:58- improper trigger mechanism under the wheels
1:02- rumble caused left dominoes to fall the wrong way
1:07- leaning towers weren’t tall enough, bridges were curved too sharply for the towers to directly hit the next one
1:11- despite it working nearly every single time before, the top section of the wall collapse mechanism overshot the collapse sections below and fell on the other side of the barrier. This fortunately hit the dominos which then triggered the stick bomb but many sections of the setup were still standing
1:23- transfer mechanism on top of the wall was too heavy and prevented the wall from falling any further
1:26- useless trigger mechanisms again
1:35- no weight in the center of the bridges to upset their balance once the counterweights were removed
1:39-1:45- wheel triggers only worked 2/5 times but were more than enough to destroy the segment. Falling planks cut off the domino line leading up to the bridge transfer
1:47- incomplete third law pairs doomed the build. This caused the huge demolition system at the base to weaken and then split in the middle which knocked the whole thing in half a second
1:51- our uneven floor caused the demolition system under one of aqueduct sections to shift which activated it. This cause the section to crash directly on the Roman pillar bases, setting off a chain reaction which destroyed everything
