You can per­form the mag­ic your­self! Reagents and equip­ment: * wa­ter; * liq­uid soap; * glyc­erin; * plas­tic pipette; * cup. Step-by-step in­struc­tions 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. Pro­cess­es de­scrip­tion 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.
