A chemically functionalised soap bubble is seen on a campanula flower (Campanula persicifolia).
Flying robots equipped with bubble guns could one day help save our planet.
That's according to a study published in iScience on Wednesday by a Japanese scientist who successfully demonstrated that soap bubbles can be used to pollinate fruit-bearing plants -- seen as vital to keeping the world fed in the coming decades in the face of vanishing bee populations.
Ejiro Miyako, an associate professor at the Japan Advanced Institute of Science and Technology in Nomi, told the media he had been working on robotic pollinators for years, but was disheartened when the toy drones he used smashed into flowers, destroying them.
"It was too sad," he said.
The whimsical idea of trying bubbles came to Miyako when he was playing with his son in a park close to their home.
The scientist was inspired when one of the bubbles harmlessly burst on his three-year-old's face.
Miyako and co-author Xi Yang first used microscopes to confirm that soap bubbles could carry pollen grains.
Next, they tested five solutions available in shops, finding one called lauramidopropyl betaine -- used in cosmetic products to boost foam formation -- resulted in better growth of the tube that develops from pollen grains after they are deposited on flowers.
They also added calcium to support the germination process and found the optimum pH balance.
Drones target flowers
The pair loaded their solution into a bubble gun and released pollen-bearing bubbles into a pear orchard -- at a rate of about 2,000 grains per bubble -- finding that 95 percent of the targeted flowers bore fruit.
Hand pollination is a much more labor intensive process.
Finally, the researchers took their experiment to the skies -- loading a bubble gun onto a small drone programmed to fly on a predetermined route.
Since flowers were no longer in bloom, they targeted a group of fake lilies.
When flown from a height of two meters and at a velocity of two meters per second, the device hit the plastic plants at a 90 percent success rate.
Miyako said he was in talks with a company for future commercialization but more work was needed to improve the robot's precision, and to potentially add autonomous flower targeting.
The study is thought to be the first exploring the properties of soap bubbles as pollen carriers, and to then link the concept to autonomous drones.

Mealtimes are a central aspect of family life, affecting the health and wellbeing of both children and adults. Although the benefits of healthy mealtimes are straightforward, helping all families realise those benefits is quite complicated, new research suggests.
“I have in my career been told many times, 'It's not your time’, ‘It's not your turn'.’ Let me just tell you, I eat 'no'' for breakfast. So, I would recommend the same. It's a hearty breakfast."
