CITC offers three different kinds of bubble fluids. Extreme Bubble produces robust and long-lasting iridescent bubbles that fly the furthest with minimal residue. Bio-Bubble fluid makes thicker, iridescent bubbles that travel long distances and are environmentally friendly. Bubble Science Formula is our most popular bubble fluid. It is in constant high demand as it produces the strongest, longest-lasting bubbles in the industry, while leaving the least amount of residue. In fact, the quality is so far above all the rest for colorful reflection and stamina, that we ship this product internationally as well. It is the number one choice for amusement parks worldwide.
