HCue: How To Make a Hollow Book Geocache

Do you consider yourself a book nerd and a geocaching connoisseur? If yes, then this HCue video was created just for you. Grab yourself some glue, a few cutting tools, and a thick book (of witchcraft and wizardry), and you’ll have all of the necessary tools to create your own “Chamber of Secrets!”

What You’ll Need:

  • Thick Book – Make sure it’s large enough to fit a logbook, Trackables, and other geocaching trinkets
  • Box Cutter or X-Acto Knife*  
  • Saran Wrap
  • Straight-Edge Ruler
  • Pencil or Pen
  • Power Drill – Optional but very helpful
  • White Glue/Water Mixture  – 70/30 ratio mixture
  • Paint brush
  • Band-aids… Just in case


  1. Select a page near the beginning of the book and use Saran Wrap to cover that page, the pages before it, and the front cover. This saved page will be used later on in the process.
  2. Firmly hold down the remaining pages and brush the outer edges with the glue/water mixture. The Saran Wrapped pages should be protected from the glue mixture.
  3. Place some sort of heavy object on top of the book and wait for the glue to dry. This should take around 15-30 minutes.
  4. After the glue dries, open the book to the first glued page. Draw 1/2 inch border inside the page edges using a writing utensil and ruler.
  5. If you have a power drill, drill a hole in each corner of the border. Using the ruler and cutting tool, start carefully cutting through the layers. Safety always comes first (as you saw in the video) so take your time cutting!
  6. Cut until you reach the back of the book. Do not cut the back cover. Then remove stray paper debris.
  7. Brush the inside edges and top of of the cut-out pages with glue/water mixture.
  8. Carefully remove the Saran Wrapped pages that you set aside step #1 and placed the saved page right before the cut-out pages onto the wet glue mixture.
  9. Close book, add weight, and let dry for another 15-30 minutes.
  10. Cut through saved page.
  11. Your hollow book geocache is now complete! You know what to do from here. And if you don’t, go here.**
