On a display marked "Intensity vs. Frequency" a sharp vertical spike was rising.

After the initial launch, the train heads up the twisted vertical spike that twists the train 180 degrees.

The train then falls and is launched backwards up the vertical spike.

The dense inflorescence is borne on a single erect vertical spike varying from 12 to 55 centimeters in height.

In addition, the wings are wider and pointed, and there is a large vertical spike behind its head, apparently prodruding from the middle of its back.

That vertical spike you can see (a 2 euro cents jump) was caused by the announcement from the central banks.

Boughs positioned as vertical spikes around street trees help discourage visiting dogs.

It had a series of wide, vertical spikes and plates down the center of its back, somewhat like the unrelated Stegosaurus.

From each he took out several lab reports that included graphs with numbered vertical spikes of varying heights along a horizontal line.

It heads backwards through the launch section and station and into another vertical spike of track, this time facing the ground.
