CHEMISTRY- FUN

This is the list of my personal favorite chemistry demonstrations and activities. These are not necessarily kid-safe activities. They tend to include pretty colors and fire. However, if you're performing demonstrations for your own pleasure or to get kids interested in chemistry, these may be just what you seek.
1. Color Fire
Anne Helmenstine
Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce a smoke that is any better or worse for you than normal smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar end result. In my opinion, this is suitable for a home fire or kid's campfire, plus most chemicals are found around the house (even of non-chemists).

2. Classic Chemical Volcano
Anne Helmenstine
This is the old-school chemistry lab volcano, as opposed to the baking soda volcano that used to be a staple at science fairs. Ammonium dichromate glows and gives off sparks as it decomposes, and makes its own cinder cone of green ash. Chromium compounds are toxic - this is a chemistry lab demonstration and not a great choice for the armchair scientist. It's still cool. It involves fire. See a trend?
