Ancient History

Some of the reactions are worth discussing with the audience. Even fairly young students will know that phenolphthalein turns red in the presence of alkali, and that the pink writing could be hidden again using a dilute acid as a spray.

Infographics redefined. A multimedia edition of Al Gore's book on climate change. I designed the interactive infographics. Some of the metal compounds such as copper, cobalt, and lead can be toxic in varying quantities and can be an irritant if the liquid is spilt or put on the skin. During World War II the Special Operations Executive (SOE) were a group of secret agents operating behind enemy lines. This meant they had to operate without being detected.

With the card, very carefully scrape the sooty substance off of the spoon and into the bowl. Do this slowly and deep into the bowl as it has a tendency to flutter away. Originally from Loveland, Dr. Carson Bruns wears several hats, including the role of an assistant professor of mechanical engineering with the ATLAS Institute at CU Boulder.
