If you bring some water to a boil, then take it off the heat and add some Koolaid and the cotton ropes, then leave the ropes to soak overnight, you can dye the cotton different colors. Useful if you're are tying two ropes together, to tell which rope is which. Or you could just buy ropes in different colors, but my way is more fun. <img src="/images/graemlins/smile.gif" alt="" />
Also, I liked Chris's post about the elephat rope. Mnemonics are often useful, but some of them are overused and forgettable. When I was learning to read music everyone memorized the Mnemonic "Every Good Boy Does Fine." However, I had trouble remembering it (Every Boy . . . Does Good Deeds?) until one of my music teachers announced, "Every Green Baboon Drinks Fresca." Well, that was a much more memorable Mnemonic! So remember, if you use mnemonics, make them memorable!
