This is fantastic! Very comprehensive. I really liked how you went from raw material to finished product, and then even gave a history of the item. I love that kind of stuff. I appreciated this video over the Popular Mechanics video because you started from the raw material and provided the history, while they just showed the industrial processes.
These must be Qualatex balloons from Pioneer Balloon Company. 5:48 It's such a pity that they discontinued the giant 36" heart; as well as GEO Blossom (5-pedal flower shaped latex balloons) and GEO donuts, even the mousehead balloons...
