Water guns are fun for kids or kids at heart on a hot summer day. With a few items you may even find around your house, you can build your own water gun with an approximate water pressure of 60 PSI and a range of up to 45 feet that will shoot water for about 15 seconds. Before you postpone your next big neighbourhood water war by going to the store, try making your own water gun.

Skill level:
Moderately Easy

Things you need

  • Juice or soda bottle (approximately 2 litres)
  • 2 feet of 1/4 tubing

  • Adaptor to fit nozzle to tubing
  • Drill
  • Epoxy glue

  1. 1

    Drill a hole in the cap of your bottle. Insert the tubing in the hole and secure with a bit of epoxy glue. Allow the glue to dry.

  2. 2

    Put the cap on the bottle and screw it so it is tightly connected. Insert the adaptor into the hose and attach the garden hose nozzle.

  3. 3

    Remove the nozzle to fill your water gun, making sure the bottle is in an upright position. Replace the nozzle, aim and pull the trigger to spray your target.

Tips and warnings

  • For an even simpler water gun, just poke a few holes in the top of a water bottle with a tack and squeeze the bottle to squirt your target.
  • Fill and use the water gun outside so you don't get the inside of your house wet.
  • Follow all warnings when using epoxy glue.
  • Be careful when drilling the lid.
