If you attended this year’s canolaPALOOZA in Lacombe, you might still be singing Don Ho’s Tiny Bubbles. The 1966 release drifted through the air alongside hundreds, if not thousands, of tiny iridescent soap bubbles.
The bubbles — and the hit earworm — were part of a spray demonstration that was organized to help producers visualize spray droplets, and how they behave in changing environmental conditions.
“So these little bubbles behave a lot like the driftable droplets in a spray cloud,” says Tom Wolf, spray application specialist. “Now all nozzles produce some amount of driftable droplets, but it’s difficult to see where they go because they evaporate so quickly.”
Wolf says the bubbles demonstrate wind speed and direction, but can also show inversions.
“If we were to release these bubbles early in the morning, when there was still a temperature inversion, they would probably hang close to the ground and they wouldn’t disperse at all, so anywhere they go, they would be able to cause a lot of spray-drift damage.”
