b. Label the part of your Experiment 2 graph where the hole in the bottle would be considered non-artesian, and explain
why you decided to label that part of the graph.
EXPERIMENT 2: What happens when water drains
from a hole in the side of a bottle?

Procedure:
1. A small hole was punched in the side of a 2-liter
plastic bottle, 6 cm above its bottom. 20
2. Tape was placed over the hole. Water Water
3. The bottle was filled with water to a height of 22 cm. height jet 18
4. The tape was removed, and a jet of water shot out in bottle distance
of the hole. The distance that the water jet shot (cm) (cm) 16
from the bottle to the table top was recorded for 22.0 10.0
specific water heights in the bottle.

C. REFLECT & DISCUSS In Experiment 2, the jet of water was horizontal for a few centimeters, and then gravity exceeded
the horizontal force and pulled the jet of water down onto the table. Water wells are normally vertical. Make a sketch of how
you would re-arrange the materials from Expeiment 2 in order to get the jet of water to flow in more of a vertical position,
like a natural artesian well, and explain how such a situation could occur among layers of sandstone and shale underground.
