My boy is on the spectrum, he needs a sensory calm down bottle/jar. I have tried a ready made one but he broke that in no time as he loves to bash it on the floor in order for the glitter to mix.
I have tried regular water bottles but he loves to open the lid and pour the water on the floor, also the plastic breaks easily.
Any idea if there is a heavy duty see-through bottles that I can use for similar conditions?
These things get inflated like baloons to produce PET bottles we usually see. They're food-safe, transparent, pretty heavy-duty and cheap. You can order them in surplus to experiment a bit and also make some spares.
Adding some soft stuff to ends will reduce damage to both bottle and terrain. You could also leave a tiny bubble of air inside - or even add some ridges/pimples on inner surface to imitate insides of a muffler if you think that water hammer adds to bottle's wear.
My best suggestion is an "unbreakable" plastic (reusable) water bottle. These can be either rigid or somewhat flexible. Rigid will probably last longer, but it really depends on how hard your son can hit. Very good quality ones should last through fairly significant damage, though, and the lid can be superglued as Drew notes in comments to the question. Perhaps a less rigid one would actually work for you, though - a Nalgene type - and less rigidity might make for a more enjoyable sensation for him when hitting it.
A bit more risky would be a glass bottle coated in silicone or in plastic. That would keep the glass shards from being a danger, at least I think it would - hence the risk... they do when dropped, but unclear what an aggressive child would do to them.
