The University of Lille team, whose findings were published in the journal Physical Review Fluids, said their research on bubbles found that soap bubbles tended to burst after a while due to “gravity-induced drainage and/or evaporation of the liquid” within the soap ball.
The team, Aymeric Roux, Alexis Duchesne and Michael Baudoin, studied soap bubbles and “fragile and ephemeral” gas marbles, a type of bubble made from a liquid solution containing plastic beads, reports UPI.com, January 21, 2022.
The researchers said they analyzed water-based gas bubbles and gas bubbles made with a solution of water and glycerol, a compound commonly used in a variety of foods and medicines.
The team says the age of the gas marble is believed to be a new world record.
The researchers say the durable bubbles they created during their project could be used to make foam stable. ***
