While rare earth elements (REE) are obscure, they are essential raw materials for a long list of high-tech products and industry groups. In many cases there is either no known substitute for REEs or available substitutes are vastly inferior. As a result of their importance in technological products, such as tablet computers and smart phones, global consumption of REEs is rising rapidly.

The reason REEs are rare is that they are seldom found in ore form in sufficient quantity and concentration to be produced economically, and there are only a handful of known deposits around the world that are rich in REEs.

As a grandparent, especially if you don't want heirs to destroy the inheritance you intend to leave, you want your grandchildren to learn basic money management as well as more advanced investing concepts and practices.

Establishing the tradition of running a money camp each year for your grandchildren can benefit you, your children and your grandchildren by enabling the learning and practice of personal finance skills.

Examples of grandma camps (where the cousins gather for a sleepover, a few days or a week of activities at their grandparent's house) abound. Likewise, examples of money camps (where tweens and teens spend a week or more participating in instructor led, hands on, finance and business activities) are plentiful.
