surface tension

People usually blow bubbles in the air using bubble pipes or plastic wands purchased from a store. That isn’t the only way to make bubbles. There are many things around your house that can be used to launch bubbles. But bubbles don’t have to float in the air; they can also be made in containers on table tops, or on top of all sorts of surfaces. All you need to have fun with bubbles is some dishwashing soap, lots of empty containers, and, perhaps most important, a sense of play. People often say that play may be fun but it is a waste of time.

Arvind Gupta invites you to explore the concept of surface tension through ordinary kitchen materials like soap water and pepper.
