Using your Plus-Plus Jellyfish tube is super easy! First, empty the pieces onto a flat surface. Let your kids start arranging them to create 2D patterns or build 3D structures like the jellyfish. Encourage them to use their imagination and come up with their own designs. When you're done playing, make sure to store the pieces back in the tube to keep them organized. Avoid letting small children put the pieces in their mouths as they are a choking hazard. Also, keep the tube away from sharp objects to prevent it from getting damaged. If the pieces get dirty, you can gently wash them with mild soap and water, then let them dry completely before playing again.
