Ecovative GIY Birdhouse




Introduction: Ecovative GIY Birdhouse

About: My name is Kyle and I like to make all sorts of things. I try to make as many practical things as possible to make my own life better and better for those around me. I like to spend time outdoors and especia…

This is an Instructable on how to make a custom shaped birdhouse using Ecovative GIY material. The materials required for the project are:

-Tap water


-Seran Wrap

-Plastic Bag

-Thumb Tack

-1 Bag GIY material

-Plastic Egg Form

The total project cost is less than $35.

Step 1: Find and Prepare the Form

I found these nested egg forms at a local department store for about $13 (see Walmart link below). There is about a 3/4" space between sizes, which is ideal for the amount of GIY material being used and to ensure there is a strong wall when the parts are finished. I used some isopropyl alcohol in a spray bottle to make ensure the forms were clean and wouldn't grow any contamination.

Nested Eggs - $12.84

Step 2: Re-animate the GIY Bag

I followed the Ecovative instructions that come with the GIY bag and are available on the internet here:

All you have to do is add water and some flour. This step takes 4 days, so be sure to account for this when making your part.

Step 3: Fill the Forms

I filled the forms in two halves, so that I could remove the plastic form from the inside before growing the two halves together. Be sure to pack the material in all the way to the bottom. Once the material is filled to the top I covered the entire thing with Seran wrap and poked several holes in the top with a thumb tack to allow the mushrooms to breath. I also poked a few holes in each of the plastic eggs to allow for additional breathing.

Step 4: Let It Grow!

After about 24 hours of growing the GIY material should be grown together enough to mostly hold its shape and pull the plastic mold off. After pulling the parts out place them in a plastic bag and attach the two halves together with toothpicks. This will provide some additional support to allow the parts to grow together at the seam. Allow the parts to grow for an additional 24 hours.

Step 5: Drying

To dry the parts, place in a conventional oven at 180F for 2-3 hours. If that isn't an option, the parts can be placed out in a dry location for 24 hours with a small fan blowing air over them.

Step 6: Cutting the Hole

The hole can either be cut after the birdhouse has been grown and dried or before the two halves are grown together.

    Very cool. Do the molds need to be plastic, or what other materials could be used? I'm wondering if papier-mache could work, or cardboard? Or do those get consumer by the mycelium and compromise the integrity of the item? Thanks!!
