Each pearl grows to approximately 3/4” in diameter (size varies on length of stay in water) Directions: Fill each vase with the desired teaspoons according to size. Once the dry pearls are added to the vase, fill each vase with water to the level you wish your Water Pearls to achieve. After approximately 4 hours, the Water Pearls will fill the vase. If left in the water longer than 4 hours, the Water Pearls can grow to a larger diameter and increase in height in the vase. Small children should be kept away or supervised at all times. Water Pearls are extremely slippery when spilled. Never flush or pour them down the drain, as the swelling could possibly clog drain pipes. Water Pearls can be used, dried and re-hydrated time and time again.

This product is perfectly suited as glass filler for our cylinders, square vases, and hurricane vases. They also can add a pop of color by adding to smaller containers like our votive holders. They easily add color and texture to any centerpiece. This product is perfect for any party or festive event, bridal/baby showers, weddings, anniversaries, office and office décor. Paired with the submersible LED Tealight, the water pearls will take on a beautiful glow. The water crystals also provide a water source when using fresh flowers as part of your centerpiece. This product is not intended for use with our floating candles as adding water on top of the water gels will make the appearance of the water pearls undefined.
