FUN AND FRUGAL HOMEMADE GIFTS

WATER ROCKET LAUNCHER

Materials:

• Valve
• 3 each ¾” PVC Cap
• One ¾” PVC Tee joint
• One ¾” x ½” threaded Tee joint
• 5’ of ¾” PVC schedule 40 pipe
• One ½” x 8” threaded riser pipe
• One ¾” 90 degree ell (“L) joint
• 1’ electrical tape
• One tire inner tube valve
• PVC pipe cement or epoxy

(important: use protective gloves and goggles when gluing!!!)

Assembly Instructions:

• With a hack saw, cut the 5’ PVC pipe into two 6”, two 12” and one 18” length.
• Drill a ½” hole in the middle of one ¾” Cap.
• Push the valve stem into this hole and trim the rubber so that it will have a tight seal.
• Glue this cap to one 6” pipe, being careful to have the pipe end push the rubber to be tightly sealed against the cap.
• Assemble the launcher as shown, glue the joints.
• Wrap the threaded riser pipe where it joins the threaded Tee, so that there is a tapered, water-tight connection when a 2 liter bottle, with a few cups of water in it, is pushed onto it.

MARSHMALLOW SHOOTER!
I found this over at TennZen. You'll love it there...go see!

The picture above is painted to suit the owner. Ours are white and boring but they work so have fun whichever way you decide to go. Painted, unpainted...they all shoot the same! :o)

What you'll need:

2 feet of 1/2 inch internal diameter PVC pipe (found in the hardware store's plumbing section)

2 PVC elbow joints to fit the aforementioned pipe

2 PVC end caps

2 PVC "T" joints

Ruler or tape measure

• 5 3-inch pieces
  
• 1 7-inch piece
