Blow molding plastic water bottles

This video is a response to Grant Thompson's water bottle challenge. Check out Grant Thompson "The King of Random"

You don't need much special equipment to blow mold plastic bottles in a home shop. If I had more time, I would have made a custom wooden form on the lathe, then made a two-part plastic mold around it, and blow molded the bottle into the plaster mold.


  1. This reminds me of a neat project I saw awhile ago. This gentlemen is taking already formed bottles, reheating them, and remolding them. Pretty neat.

  2. Cool stuff... I once had a summer job pulling pallet sized boxes of thousands of those pre-forms off of the press. They were shipped out and molded on site where they were filled. I never imagined they could be done so easily at home.

  3. Awesome! Hi, it's me Mostlymacros from Utube. I asked you for some questions about an SEM build. I have facebook but could not find you there, I don't have Twitter. So if you could please email me through the email on my blog: "" that would be great--when you have some spare time. If you want to swap links I will put a link to your blog in mine. I have 1000s of photos and videos to post of electronics experiments and projects, I fear my blog right now does not do much of it justice but I built all the stuff on there and far far more. Anyways-- as I say I have a lot of tube experience but none with photomultiplier tubes although I am aware of how they work and the basic idea. I think the only way we will be able to correspond is email, so if you could please email me via the address in my blog just Google "Mostly macros" --or my blog is the first one to come up under that name. Thanks a lot-- G.Beasley
