Notes

Use room temperature water for best results. Avoid vigorous shaking to maintain the storm effect. Store sealed at room temperature and shake gently before viewing. Swap vegetable oil with baby or mineral oil for different effects. Add essential oils to the oil layer for scent. Try different food coloring shades or add plastic shapes for variety.
