Storm Glass Barometer Setup
1) Fill a container with water — use distilled water to help prevent streaks on the glass.
2) Add food coloring to the water to make it easier to see.
3) Push the injection tube onto the syringe (shown below).
4) Fill the syringe with the colored water.
5) Insert the injection tube into the spout of the Storm Glass. The tube should go
completely down the spout and stop at the top of the glass chamber. DO NOT
INJECT THE COLORED WATER AT THIS TIME.
6) Hold the Storm Glass with one hand while holding the syringe with the other. Turn
the Storm Glass upside down.
7) Slowly inject the colored water into the Storm Glass until it is about half full (shown
below).
8) Remove the injection tube from the Storm Glass.
9) Turn the Storm Glass back to its upright position and set it on a at surface.
The water should be about 1” up the spout of the Storm Glass. If the water is not at this
level, ll the syringe with air and insert the lling tube back into the top of the water
chamber. Do not turn the Storm Glass upside down for this procedure. Inject air into the
chamber.
Water will rise up the spout and may overow. You may want to do this over a sink
and have a cloth or paper towels handy for clean up. Once you remove the injection
tube the water should be further up the spout. Once lled, the water in the spout will
immediately respond to changes in barometric pressure. Some evaporation may occur
over time and additional water can be added as needed.
