School science fair coming up? Don't worry: We've got step-by-step instructions to dozens of science projects in this Howcast video series, including how to build an erupting volcano, how to make glow-in-the-dark art, how to make a weather barometer, how to make disappearing ink, how to make 3-D glasses, and how to make a marshmallow gun.

 
 

You Will Need

  • Battery Operated Alarm Clock
  • Motorized Water Gun
  • 16 Gauge Wire
  • Wire Stripper
  • Voltage Relay Switch
  • Breadboard Circuit
  • Soldering Equipment

Steps

  1. Step 1

    Open the clock

    Open the alarm clock and snip the 2 wires that lead from its circuit board to the speaker.

  2. Depending on the clock’s design, you may need to snip the wires just to get it open. That’s okay.

  3. Step 2

    Strip wire

    Strip the two ends of wire leading from the board, and splice two longer pieces of wire to the ends.

  4. Step 3

    Solder

    Solder these splices to secure the connection.

  5. Step 4

    Snip watergun wires

    Take apart the water gun and snip the two wires leading to the trigger switch.

  6. Step 5

    Strip wires

    Strip the ends of these wires, splice longer wires to each end, and secure the connections with solder.

  7. Step 6

    Connect wires

    Pop the relay switch into the breadboard circuit and connect each pair of wires to opposite sides of the relay.

  8. If you don’t have a breadboard circuit, solder the switch and wires to a regular circuit board. It’s harder to do, but will make for a more permanent connection -- and water clock.

  9. Step 7

    Set alarm

    Now set the alarm, position the water gun so it’s pointing at your face, and drop off into a nice peaceful sleep.

  10. Sleepers who rely too heavily on the snooze button deprive themselves of valuable REM sleep, impairing their mental functioning during the day.
