Make crayons from scratch. It sounds like a tedious process, but in actuality it's a very fun project that is fairly simple. I used the crayon recipe from Wee Folk Art and the crayons came out perfectly. Instead of using round molds that the recipe suggested, we used an animal mold that we already had. After it was all said and done, we had animal shaped crayons that the kids adored.The activities were not only educational and fun for my children, but it was definitely a stress reliever for myself. Now that we've made crayons from scratch, my kids no longer want to buy them from the store (well, my 19-month old doesn't care either way). Another great thing I realized was that we could make candles from the crayons and give them as gifts. So if you're looking to have some fun with your kids, regardless of age, this will definitely be a hit!
Make crayons from old crayons. Yes, reuse your old crayons to make new ones. When I was a child, I remember throwing away half broken crayons (not so eco-friendly). Ironically, my daughter does the same thing, so when I discovered that you could make crayons out of old crayons on Planet Green, of course I had to try it out. Not only was is straight forward and easy, it didn't cost me a penny.
Make candles from old crayons. I would have never guessed to make candles from old crayons, but it does make sense since they both involve wax. The steps are pretty straightforward as written by Kathryn Vercillo, but you do have to be organized. The only materials you would need other than crayons are the plastic wax-melting bags, candle molds (or your own baking molds) and wicks.
