Need a place to hide your valuables? Try making my secret diversion safe that looks like a full jar of popcorn kernels! It costs about $1.00 to make, which is so much cheaper than diversion safes carried at spy and detective shops. Don't have popcorn? You can use whatever filling that won't look too enticing: lentils, beans, bran flakes, etc. The possibilities are endless.

Total Time: 30 minutes

Yield: 1 safe


  • 1 empty water bottle
  • 1 jar with a wide opening
  • 1 marker
  • scissors
  • popcorn kernels


  1. Peel the label off the bottle and dry the inside.

  3. Stick the water bottle inside the jar. Use your marker to draw a line on it right at the lip of the jar.
  4. Cut the bottle right below the line. Discard (or recycle) the top of the bottle.
  5. Place the lower half of the cut bottle into the jar. Use your fingers to push the bottle inwards, then pour some popcorn kernels into the sides of the jar.
  6. Shake it in circular motions to fill any gaps.

  8. Keep filling until it looks 100% full.
  9. Place your valuables inside.
  10. Screw the lid on the jar. Your valuables are completely hidden!
