Got hose? Got sticks? Build a dome!

So I was working on a garden bed and looking overy irrigation supplies.
I have a lot of short lengths of hose, and it made me think of this geodesic dome hub design:

Basically the author uses irrigation tubing to form hubs and bamboo for the struts.
It's designed to be a teaching tool.
I mostly have chunks of garden hose, but I think it could work.
While the resulting dome wouldn't be capable of holding much weight, it will probably be stable.
I happen to have a huge supply of finger width mulberry branches that I would probably use instead of bamboo.

Depending on the results you wanted, you could cover the entire strut with a piece of hose longer than the strut, then flatten the hose at both ends.

Taking this idea even further, you could slide your strut into an old inner tube, leave plenty of  extra tube on each end and  tie knots, making a "strut sausage" with a rubber inner tube as the "casing" .
Tie the resulting ends together  to form your hubs.
If the strut is wood, maybe toss some borax in there with it.


Since you have inner tubes,can you just inflate them and use them as struts?
Like a geodesic dome made with balloon animal balloons.
Can you join them together in a way that allows you to inflate the whole thing at once?
Could you fill it with spray foam?

Ok, I think that's enough for now.
