High quality soda siphon. Must get water down to 34 degrees or colder before filling to ensure successful carbonation. Instructions are somewhat difficult to understand, but the illustrations make things clear. After charging system with gas, then shake immediately and you must remove the gas cartridge to prevent leaking gas. Refrigerate system for 30 to 60 minutes maximum, and then before serving carbonated water shake again many times to get best results.
