This form of cryogenics are not surprisingly becoming increasingly popular. They project a plume of powerful white fog for up to 3m, combine this with their accompanying sound effects and you'll add a punch to any production. Co2 Jets are completely safe and leave no choking smoke, stains or smell as the plumes dissipate immediately. The coolness of the decompressed Co2 will reduce surrounding temperatures whilst adding a blast of refreshment to the crowd.
