Step 6 Creating the sounds

To sound like a volcano, I mixed sounds I found on the net. What you hear in the video is a combination of a fireworks show, bubbling soup, and rolling thunder. To play the sounds, I used an I-pod nano hooked up to an old set of computer speakers. The nano played a continuous loop of the sound effects and when the power was turned on via the remote, the speakers turned on and the sounds could be heard clearly even in a crowded bowling alley.

The picture here shows how everything fit into the box.
