Introduction: Mini Water Fountain

Hi All,

In this instructable, I will share how to make a mini tabletop water fountain at home. We will be using thermocol or foam, Which came as packaging material for modular furniture and some old food boxes

Primary Objective for this design

  • Should be simple to make, with no special skills or tools
  • Reuse old themocol that I have been collecting for years
  • Reuse some of plastic food containers
  • Should be able to make with my kid, to keep him busy in lockdown


Step 1: What Do We Need ?

  • Thermocol or foam
  • DC 3-6V water pimp
  • 6mm tube
  • old USB cable and a charger
  • Black and bronze acrylic paints
  • Clear coat or varnish
  • Pebbles
  • Soldering Iron
  • Paper cutter

Step 2: Cutting

  • The the project we need to cut thermocol into following sizes
  • 2 pieces of 12 x 18 cm
  • 1 piece of 6 x 18 cm
  • 1 piece of 9 x 13 cm
  • 4 pieces of 7 x 3 cm

Step 3: Front

  • on a 12 x 18 cm thermocol piece, draw lines separated at 1 cm
  • Using hot soldering iron, curve along these lines as shown
  • Do this gentling, as the thermocol could melt away too fast and one needs to mind the dept of the curved parts
  • Do not worry if the lines are not in a straight line, it give it a natural look

Step 4: Tank

  • Curve a tank and route for tube on the front and back pieces
  • Hot glue the pvc tube on one of the piece as shown
  • Cover the tube opening at the tank with hotglue to avoid any leaks

Step 5: Building

  • Using hot glue stick the front and back together
  • Then hot glue curved thermocol on the front side as shown
  • Stick the base (13 x 9 cm)
  • Cover the fountain with thick paste of white cement
  • Let it to dry for 12 to 18 hrs

Step 6: Wiring

  • At the bottom of the fountain, fit the a dv pump
  • Connect the pump's +ve and -ve wires to a USB charging cable
  • Typically Red is +ve and Black as -ve

Step 7: Finishing

  • Before you finalize the fountain, test it.
  • I notices that the water would split out of the tank
  • I added a piece of thermocol on the top to set the water direction and avoid overflow
  • Here I have painted the whole fountain with Black acrylic and then dry brushed bronze paint on it
  • After it drys, use clear coat or varnish...
  • Note that some of the varnish can damage/melt thermocol
  • Set the fountain in a black food container, add pebbles and water.
  • Switch it on and enjoy the water fountain smoothing sound
