Parents' and educators' guide
For the benefit of parents, educators, and anyone working on these projects with younger people, I have attempted to categorize them by relative safety. Note that these are only my opinions, and in no way does this imply that any of these projects are "safe" or intended for children! As has been stated before, this site is a museum of projects, and not necessarily a "how to". Please keep in mind that I am not an educator, so use your best judgement on any of these projects before attempting them yourself or, especially, with children.
At the bottom of each project page is a symbol or group of symbols that give an estimate as to the level of the project, as well as certain potential hazards involved with the projects. They are defined as:
Kid safe - These projects are relatively safe and usually appropriate for younger children. Note precautions accompanying individual projects.
Moderate - Appropriate for older children. They may involve some electricity, chemicals, or other component unsuitable for young children.
Advanced - More difficult projects, as well as those involving dangers of electricity, toxicity, etc.
dangerous - Projects listed for knowledge basis only. These are best left well enough alone. Stay away!
More than one of the above
symbols appearing on a page indicates a range.

Electricity involved. Electricity can cause severe injuries or even death, so take all possible precautions.
