How to measure wind speed and direction using bubbles
Equipment
- bubble blowing kit
- stopwatch or phone
- compass or a compass app
Bubble Chase to Measure Wind Direction
- Place a marker at your start location. Choose an area of open ground which is safe and away from roads.
- Blow some bubbles then pick one to follow.
- Chase your chosen bubble, without getting in its way, until it pops or floats somewhere you cannot follow.
- Blow another bubble from where you end up and follow that one.
Wherever you end up, look back at where you have come from.
Now use your compass to work out the direction back to the starting point. This will give you the wind direction, because wind direction refers to where the wind is blowing from.
Repeat a few times if possible.
