It’s been some time since I had a chance to post anything on this Blog. Work and life has a tendency to eat into your geocaching time. To make up for the absence  I decided to document my latest cache creation: Beware The Blob! Geocaching in Pennsylvania was never so much fun!

We start by gathering all the materials needed for the project:

In the above photo, I used some modeling clay purchased at a local big box arts and crafts supply store. I also used some common cling wrap, easily found at your neighborhood grocery store. The tube of toy figures for the blob’s victims came from another art supply store. The cache container itself was also found at a local grocery store. Finally, the tube of MS Polymer from Soudal can be purchased through Kraftmark .

Looking at the above picture, we see how the container is first wrapped in the cling film. Then clay is piled around the container to avoid any undercuts which would make it impossible to pull out of the blob. Blobs can be hard to extract!

Using a standard cartridge gun (Not pictured. Use some imagination here), the MS Polymer is extruded over the wrapped container and smoothed around. The Polymer is very thick, but can be manipulated with a craft stick or disposable trowel.

The polymer is allowed to settle into place before putting in the victims:

After curing overnight, the container is pulled from the finished blob:

Flipping the blob over we find a void perfect for fitting the container cache:

Which slides right into place.

The blob cache is placed in a secure location and the coördinates listed on a favorite geocaching site. I put this one in a remote section of a wooded area. Didn’t want any enemy agents finding it! Also didn’t want to scare the locals. It was found within 24 hours of the hide.
