Summer Fun (in Less Than 2 Hours)

It's a skill so useful for sailing, camping or just looking cool and capable. Hit the hardware store and invest in four feet of inexpensive, easy-to-manage 1/4-inch to 1/2-inch nylon rope per child and adult. Instruction is particularly effective if one sibling ties up another sibling or father...(Keep at least one other parent, guardian, sentient adult within shouting distance to avoid a grown-up learning a lesson the hard way.)
