With my 16 year old son, I built a weather balloon with one, including an Arduino, a few temperature sensors, a GPS, LoRA radio, and we're going to launch it next month. Having a hard time finding Helium.

As a further science project, why not liberate hydrogen through electrolysis? Much less expensive than helium, and greater lifting capacity...

good idea! I think we're just going to get a hydrogen tank, some protective gear, and go that route.

Don't most party stores have helium tanks?

I need 200 cubic liters and they won't sell that much

Welding supply store may be worth checking.

Yes they won't sell except to existing customers. New customer == no helium.
