Using the ZURU Bunch O Bubbles Mega Bubble Blaster is super easy. First, take the included 250 - ml bottles of bubble solution and pour it into the easy - refill holder. Make sure the holder is not overfilled. Then, turn on the blaster. It will start creating a continuous flow of bubbles at an amazing rate of 15,000 bubbles per minute. The LED lights will add a fun touch to your bubble - blowing experience. When you're done, turn off the blaster and store it in a cool, dry place. Keep the battery charged by using the included 3.7v 1300 mAh Lithium Rechargeable Battery Pack. Avoid getting the blaster wet when it's not in use and clean it gently with a dry cloth if it gets dirty. Don't forget to replace the bubble solution when it runs out to keep the bubble - blasting fun going.
