Need an Idea! (Science fair stuff)
Gents, I have a very close friend for whom I am the closest thing he knows of to 'a science guy'. I'm not a very good 'science guy' but I'm better
than, say, Leticious in Accounting.
He's trying to help his 13 yr. old come up with an idea for a project. It's got me stumped. I thought you all would be a veritable El Dorado of good
ideas. The project is, "improve something through chemistry" The parameters are:
• The technology has to involve Chemistry
• It has to be practical – it has to do a job
• It has to give the impression that it is improving something or creating something new
• It has to be simple enough for a brochure to be turned in this Thursday and a prototype to be built by next Thursday

Produce Sulfur with the Barking Dog. Stinks out the room, so he's the only one left to receive an award

the object of his search.
I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.”

As they say a good plan now is better than a perfect plan later.
I don't know how much of even theoretical " hazard " is
tolerated these days but fire and brimstone seems pushing it.
Clear plastic chips from soda bottles can be melted in a
small metal dish on an electric hotplate to the point it emits
fumes. Caution it is combustible. The point here is that a
sample of cotton cloth can be made water repellant by a
light application of the fume. A portion of cloth can be
secured by a rubber band over one end of a segment of
sheet metal air duct about 6 to 8 inches long and the open
end placed over the heated dish on the hotplate. After a
period of 1 - 2 minutes the treatment should render the
desired property of water repellence to the fabric.

Good point. Especially in OP is in the USA.
