Petroleum jelly is unable to detonate without the use of a blasting cap. It was used as a stabiliser in the manufacture of the propellant Cordite. Petroleum jelly can be used to coat the inner walls of terrariums to prevent animals crawling out and escaping. A stripe of petroleum jelly can be used to prevent the spread of a liquid. For example, it can be applied close to the hairline when using a home hair dye kit to prevent the hair dye from irritating or staining the skin. It is also used to prevent diaper rash. Petroleum jelly is used to gently
Jelly-falls can lead zones around jelly-falls to become hypoxic and inhospitable to larger scavengers. Researching jelly-falls relies on direct observational data such as video, photography, or benthic trawls. This means that jelly-falls are not always observed in the time period in which they exist. Because jelly-falls can be fully processed and degraded within a number of hours by scavengers and the fact that some jelly-falls will not sink below 500m in tropical and subtropical waters, the importance and prevalence of jelly-falls may be underestimated. Jelly-falls Jelly-falls are marine carbon cycling events whereby gelatinous zooplankton sink to the seafloor and enhance carbon
