Product details:

Tekno bubbles are patented, safe non-toxic blowing bubbles that look and act like normal bubbles under regular lighting, yet are unlike any other bubbles in the world. Gold tekno bubbles have a beautiful, brilliant glow under uv blacklite lighted conditions. Wand not included. Great for bubble machines. Size: gallon bottle, color: gold best results are achieved with 365nm blacklights i.e fluorescent, mercury vapor, or metal halide. These do not respond well to led style blacklights that are in the 395nm-405nm rage.
