Fobbles Bubble Fluid is designed to create sturdy, colorful bubbles filled with fog. The surface tension of these bubbles is strong enough to handle being filled with fog and will last a long time in the air before eventually popping wth the amazing “Poof” of Fobbles. The exterior of the bubble is made to be iridescent and colorful, meaning every part of the Fobbles display will be as visually appealing as possible.
