Simple Comet Model
Here's a simple way to make and only for you display a humble model of a comet. Insert some light colored pipe cleaners into a styrofoam ball, with the ball representing the coma and the wires the dust tail. Include a blue appendage for the canada pharmacy chewable viagra blue ion tail, which always extends directly opposite the sun, downwind of the solar wind. Suspend the model with a piece of monofilament line that is tied to a wire tail near the foam coma.
The images shown were from a day camp at St. Vincent de Paul in South Bend, IN, at which the young participants created innovative tails.
(The simple comet model is also the basis for a car antenna decoration. After 500+ miles of highway testing, a prototype is still hanging in there. Image.)
