Pour water and liquid soap into a glass cup, and add glycerin. Mix the solution. Put on woolen gloves. Take a pipette, cut off one end, dip it in the solution and start blowing soap bubbles. Take a bubble in your hand and play with it, tossing it from one hand to another.
Why doesn’t the soap bubble burst? The glycerin makes the wall of the bubble denser and stronger. And the area of contact of the bubble with the glove is reduced thanks to the wool, and so the bubble doesn’t burst for a long time.
