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
- A clothespin
- Some aluminum tape
- Some red electrical wire
- Some black electrical wire
- A wire cutter and stripper
- A battery-powered noisemaker
- A 9V battery
- A 9V battery holder
- Some fishing line
- A sheet of paper
Wrap aluminum tape around clothespin tips
Wrap aluminum tape around both tips of the clothespin, leaving a tab on each end so you can attach wires.
Tape electrical wire to clothespin
Cut a piece of black electrical wire, strip both ends, and tape one end to one tip of the clothespin.
Connect negative pole to other tip
Locate the wire running from the negative pole of the noisemaker—the pole marked with a minus sign—and connect it to the other tip of the clothespin.
Connect wires to battery holder
Locate the wire leading from the positive pole of the noisemaker and connect it to the battery holder. Now do the same with the remaining black wire coming from the clothespin.
Fold paper & string fishing line
Start folding your sheet of paper into a triangle, but stop halfway. Now string the fishing line across the strongest crease, tie it off, and finish the triangle.
Put folded paper inside clothespin
Put the folded paper inside the clothespin.
Tape to inconspicuous place
Tape the clothespin, noisemaker, and battery to an inconspicuous place in your coworker’s path.
Run fishing line to secure anchor
Run the fishing line to a secure anchor across the way.
