- Disposable Cup - Permanent Marker - Blue Tape - Concrete Mix - Large Mixing Bin
Step 1. Prep The Tubes For The Base Of The Mushroom First, if there’s an attached bottom, remove it. For one tube, I could easily push it out from the inside.
Step 2. Secure The Cardboard Tubes Glue the tube to a base. I used a tile because it is flat and easy to demold. Heat a glue gun, and then run a thick bead of glue around the tube to secure it.
Step 3. Mix The Concrete For The Mushroom Base Use a large mixing bin to mix the concrete. The consistency of the mix should be like crunchy peanut butter with a lot of extra peanuts added.
Step 4 . Prep The Mold For The Cap Of The Mushroom First, add the oil-based clay to the holes in the plastic bowl or dome. The opening where the holes start is a little recessed from the bottom.
