One of the most challenging things I have ever done is attempt to build something with dominos, while a four-year-old is present. Last night I managed to capture this sequence showing successful completion. The first frame shows the final piece being placed on top, with instructions being signed anxiously. Next we see the happy conclusion, followed by some jumping and the entrance of a big sister. In the final frame, the tower is leaning precariously. It toppled before a subsequent frame could be captured.

Dear Bopop,
Thank you for inviting us to your house for your birthday.
With love,
Abby
The structure represented by the assembly of dominoes is called a column; the classical failure mode of a too-slender column (such as this one) is called "crippling", where the middle of the column displaces to one side, thereby reducing the ability of the column to support the weight above. In the pictured sequence, the weight is simply the upper parts of the column itself.
Conclusion: Faulty design -- should have been broader at the base and tapered upward. Consulting fee waived.
