Touch this one with a dry finger. Blow gently on the other end to form a bubble. You can use wider tubes such as coffee cans to make still bigger bubbles. Look closely at the bubbles you make. If you have a wand at home that is left over from a bottle of bubbles you bought at the store, you can use it with this bubble solution.
Bubbles are bits of air or gas trapped inside a liquid ball.
The surface of a bubble is very thin. Bubbles are particularly fragile when a dry object touches them. That's because soap film tends to stick to the object, which puts a strain on the bubble. So if you want your bubbles to last longer, keep everything wet, even the sides of the straw.
