To use slime effectively, start with clean hands and a smooth surface. Knead and stretch the slime to improve its consistency and remove any air bubbles, experimenting with different textures and recipes to find what suits you best. Store slime in an airtight container to prevent drying out, and avoid mixing it with other substances to keep it clean. Clean up spills promptly with warm, soapy water, and supervise young children when they play with slime. Get creative with your slime play, whether it's stretching, squishing, molding, or using it as a stress-reliever. Ultimately, the key is to have fun exploring the sensory experience that slime offers!
