Help!!!!!! I have to come up with a chemistry project topic but I can't think of anything not too dangerous or not off-topic! I need an A+ idea ASAP. My hypothesis, outline, etc. are due by tomorrow but I need your ideas now! Please help in anyway you can! It's STRICTLY chemistry! And I have to be finish my outline in 3 hours from now! Thanks!

Polymerization: The formation of long molecules due to the interaction of smaller fragments of molecules with each other.
Preparation of silly putty, borax (a detergent) with Elmer's glue in a solution of water.
You can check the web on how to do it and explanations of the process are typically explained in those web sites.
That is as much as I can tell you without actually doing your project for you. You need to do the rest.

How to dye fabrics in a way that is fast to washing. The materials for this project should be easy and cheap to buy. Yet they should not be commercial dyes (All-Purpose Rit), because no one knows what those are.
Materials: Dyes from the supermarket: Turmeric and saffron from the spice aisle.
Fabrics from a fabric and sewing store. Get white cotton, silk, wool, acrylic, polyester, rayon, nylon. Avoid blends. Do not use polyester/cotton blends, etc. You want pure samples.
Mordants: These are compounds that "help" dyes onto the fabric. Cream of tartar, ammonia (no soap!), vinegar, alum if you can get it.
Method: Cut fabrics into 4"x4" squares and label each (staple something to each). Treat each kind of fabric with nothing (water), vinegar, ammonia, cream of tartar solution, and alum.
Dye each swatch with either saffron or turmeric solution. Dry. Wash each swatch every day. Let dry. Wash and dry again and again. After several washings and days, there should be differences in the retention of color by each kind of fabric of each kind of dye according to the mordant that was used.
Conclusion: Look up each kind of fabric. Lookup each dye. Look up the mordant compounds. Draw conclusions. Walk away with an A+.
