These jelly beads are incredible! This jelly décor is a water-absorbent that can hold about 100 times their weight in water. You just apply one pack of jelly in about 1.0 quarts of water and allow to fully expand in 6-8 hours. Remove the expanded beads and pour into vases or bowls. One package may fill aproximately up to three 16" eiffel tower vases. This is an awesome way to turn your decorations into beautiful and unique centerpieces!
