How can glycerin be used to enhance the longevity and quality of soap bubbles?

Glycerin can be added to soap bubble solution to make the bubbles last longer and be more durable. This is because glycerin helps to slow down the evaporation of water from the bubble, making it less likely to pop quickly. Additionally, glycerin can also help to make the bubbles stronger and more resistant to breaking, resulting in higher quality bubbles that can float for a longer period of time.
