Everyone comes up with cool ideas of ways to jump out and scare people for Halloween.

But few are able to make the best of those ideas a scary, Oct. 31 reality.

Reddit user calebkraft—you might know him as Caleb Kraft, community editor for Make magazine—does not fall into that camp, and thankfully, he’s willing to share his knowledge and expertise with the DIY community. That’s where he posted his step-by-step process to create giant, inflatable tentacles that can be used to decorate the home for Halloween, Valentine’s Day, Arbor Day or every day. He even linked to a YouTube video of the process that he did for Make.

Other users even offered their own suggestions, which Kraft encouraged.

Kraft fielded practical questions and safety concerns about building the tentacles, as well as revealing the secret reason for creating them (he did it all for Cthulu). And was all the work worth it for Kraft?

That fact seems pretty evident.
