I don’t know about you, but I am a big fan of homemade kebabs. Making them at home does not have to be challenging. Roman UrsuHack has shared a guide that shows you how to build a simple device to make Koobideh Kebab on skewer sticks at home. You are going to need a plastic bottle, an empty can, pipes, drill bits, and a few other parts to get started.
Once you are done, fill the bottle with ingredients, press down the can, insert the stick, and push. It’s not perfect but seems to do the job well enough. More information is available here.
