Camelbacks are extremely useful for hiking, fishing, airsoft/paintballing, and many other outdoor activities, but the average $30 price for a decent one is a little too expensive for many. I made a few of them for under about ten dollars minus the bag and sodas.
Step 1: Materials and Tools
You will need a:
*Hot glue gun with glue
*2 Liter Soda Bottle
*3/8 " Rubber Tubing
Step 2: The Cap
Poke a hole into the cap with the Phillips screwdriver and widen it out with the scissors to fit the cap snuggly.
Step 3: The Rubber Tubing
Cut the rubber tubing to fit the size of the bottle and the person using it.
Remember to let tubing touch the bottom of the bottle so it can all of the water.
Put the tube through the cap and twist it onto the bottle.
Step 4: Gluing the Cap
Warm up the glue gun and glue around the edges of the tube to prevent from water dripping out.
Tape also works but I found glue looks cleaner and more efficient.
Step 5: The Pouch
Slide it in the pouch and you have made your first rigged "Camelback."
