This heavy and highly pressurized K-Cylinder contains Hydrogen. The same Hydrogen that would be used to launch weather balloons. So you have to lug this huge cylinder around which is unsafe for 1 because it extremely high pressured and 2 its extremely heavy when full.
Now our 32 Oz Can can fill up a weather balloon even better then a K-Cylinder via the Portable Balloon Inflation System. These cartridge like cans can be stored and are a ton safer then this K-Cylinder. 10 of these 32 oz cans can do just as much as this huge K-Cylinder.
