Welcome to a Series of experiments using basic items around the house that help you measure the weather outside your own front door!
Each experiment also includes a quick trick for measuring that part of the atmosphere! Tag me on social media photos and data as you track the weather outside your own front door!
HOW TO BUILD A BAROMETER
What you need:
- Plastic bottle
- Ruler
- Food coloring
- Bubble Gum
- 16” of tubing
- Water
What to do:
- Fill a plastic bottle with water half way and tape the ruler inside the bottle.
- Add food coloring.
- Add the tubing to hang over the top.
- Suck it half way up and put the gum on the end.
As it gets warmer or colder, record when the water rises and falls and then compare to the weather.
Notice the weather happening over head when the pressure rises and falls. Low pressure brings stormy weather while high pressure brings clear skies.
Barometer History: The mercury barometer was invented by the Italian physicist Evangelista Torricelli in 1643.
Quick trick tip — just ask your friends who can “feel the weather.” It’s a real thing!!! Pressure Changes: Some people say they can feel weather in their bones – it’s thought that the pressure change of an approaching storms can cause this physical warning!
