Materials
3 1/2-inch-diameter PVC pipe, qty. 1
3 1/2-inch-diameter PVC test plug, qty. 1
3 1/2-inch-diameter PVC end cap, qty. 1
Container each, PVC primer and cement, qty. 1
Can spray paint, qty. 1
Step 1
Measure and mark off with a Sharpie the length of the pipe necessary to hold your contents. We chose 14½ inches.
Step 2
If the child is at least 12 years old and has some experience, with careful adult supervision she can use a miter saw to crosscut the pipe. If not, a standard eight-point carpentry handsaw is a safe alternative.
Step 3
Apply PVC primer to the end of the pipe and on the inside of the end cap. (Be sure to open the windows for ventilation.)
Step 4
Using the applicator tool, spread a thick layer of PVC cement onto the end of the pipe, and a thin layer on the inside of the end cap.
Step 5
With the PVC pipe upright, tap the end cap on with a dead-blow hammer or mallet. Twist the end cap slightly to evenly distribute the cement, then finish tapping the cap until it is firmly seated.
Step 6
Fill the time capsule with whatever you like, preferably nonperishable. Be sure to include something that indicates the date of the contents.
Step 7
Insert the test plug into the pipe and wind the wing nut until it is firmly tightened.
Step 8
Spray-paint the capsule.
