Fishing Rods

I know it seems stupid or obvious, but exactly how are the helium rods made? or is it a secret? I just want to know how y'all added the helium or it just real light blank and you call it helium.

The name ( - - blocked - - ) about because of how light our rod creation ended up weighing in after final prototypes had been fished with. Helium was kind of a nick name at first but everyone thought it fit the exact description for the light weight feel. After that, a prostaffer ( - - blocked - - ) up with the Lighter Than Air slogan for us. I wish we could contain He gas inside the blank, but we have actually tried and it is not possible.
Thanks for asking,

Thanks, Make sense to me.
