Drink carbonator
(feddit.uk)
A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!
Guidelines:
Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!
Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.
Videos links are not allowed as post titles, but you may use them in a text post.
A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:
The homebrewing community (at large) does a lot of carbonating, so that’s a good place to research and get equipment.
That DIY option looks like a good option. Avoid glass, and/or keep it in a solid box while charging and you should be fine as far as safety. Poisoning is hard to accomplish.
You could also get a small keg and refrigerator.
