How to Make a Time Capsule

SAFETY FIRST: Ask an adult to help with tools you haven't used before.

Use a PVC pipe to make an indestructible time capsule that will keep your treasures safe for years.


  • One pre-cut PVC pipe 4 inches in diameter (We recommend 1 foot in length, but you can make yours larger or smaller, depending on how much you want to store in the time capsule.)
  • Two 4-inch plastic test plugs
  • Items that represent you
  • A retrieval date (when you will open it)
  • A storage location
  • Stickers, paint, duct tape and any other items to decorate the time capsule


Step 1: Gather items to store in your time capsule: action figures, toys, a local newspaper, your favorite magazine, a current photo, a sports card, a letter to yourself in the future, patches and anything else that represents you. Don’t include food or anything that might attract pests.

Step 2: Decorate your time capsule using stickers, paint, duct tape and other things you think look cool. Be sure to add your retrieval date on the outside. Mark your calendar with or make a note of your retrieval date.

Step 3: Construct the time capsule. Insert one of the plugs into an open end of the PVC pipe. Twist the wing nut until the plug is secured. Place all your items in the time capsule. When you’re finished, insert the other plug and twist the wing nut until the plug is secured.

Step 4: Store your new time capsule in an out-of-the-way location, such as under your bed or buried in your backyard.

      Pretty much any hardware store should have them for a 4″ pipe. You could always use a cap for one side and a plug for the other.
