Petra stacks some tables

After looking around the room and at everything at her disposal, Petra moves one of the buckets to the ground so she can use the small table it was on.

She stands the table on the model, and its legs are just wide enough to span the river.

She then abandons this idea, instead moving the entire model itself to the floor, so she can use the large table on which it was presented as her bridge.

Petra then stacks one of the smaller tables on top of the large one, though she is worried about the fact that her bridge is now leaning at an angle.

She then starts to spread dry sand over everything, declaring that the bridge shouldn't need much sand before it can be called a ‘sand bridge’.

Finally, she provides additional support on either side of the large table by leaning two stepladders against it.

Petra is disqualified, however, after it is determined that she did not build a qualifying sand bridge.
