Golf ball pyramid - how to keep it together for a garden ornament

[Nightsky224]

I want to make a pyramid out of golf balls as a garden ornament. I did one years back but it was small. I heald it together with some kind of caulk i think. It has stayed fine and still in the garden. I want to make this one but a lot bigger. I tried but the caulk i used just went soft like chewing gum and all fell apart. Any ideas what I could use that would withstand the weather (cold and hot)...

Silicone? Or CT1 adhesive?

and CT1 like this https://www.amazon.co.uk/CT1-0304423-Sealant-Construction-Adhesive/dp/B00F8CK7T4
Any idea which would be better?

CT1

thread the balls on a stiff wire frame, problem is drilling through the balls will not be easy

Hot glue gun .Caulk is not weather proof .

 

[Nightsky224]

Someone above has suggested CT1 do you think that would work better than the hot glue, worried about the cold weather?

Either should be fine in cold weather but the hot glue goes off in a few seconds which may or may not be a good thing ....

Instead of making the pyramid just from golf balls, it could be made much bigger, using the same number of balls, if a hollow pyramid were first made from triangles of water-proof panels with the balls then fixed to that.

Very true but less fun
