Enter the fascinating history of Colorado Springs’ founding estate. How did a refined English Tudor-style castle come to exist in the vast, unsettled West? Created by railroad tycoon and Civil War General William Jackson Palmer, Glen Eyrie Castle is adjacent to Garden of the Gods and the iconic views of Pikes Peak. Brand new archeological findings reveal intriguing details of castle life!


Ladies of the Mine

High altitude, groceries delivered by mule train, pack rats and spoiled Thanksgiving turkeys are just a few of the challenges faced by ladies living in Colorado's remote mining towns at the end of the 19th Century. Learn the stories of three inspirational women who held their own while surrounded by a harsh landscape and un-lady-like company.


Suffrage

On November 7, 1893, Colorado became the first state in the nation to grant women’s suffrage by a single issue popular vote, and the following year the first three female state legislators were elected. Meet the dedicated Colorado women that led this charge. Today, Colorado has the highest percentage of women in the state legislature.


KKK

From the Grand Dragon to known KKK appointees in the police, mayor and governor offices, Colorado once had the 2nd largest Ku Klux Klan membership in the United States. Discover the sordid history of the KKK in Colorado and the impact they had on Catholics, Jews and African Americans in early 1920s, and the courageous individuals who fought against their establishment.


Cheers to Beers!

The history of Colorado may best be seen through the bottom of a beer mug. From quenching the thirst of Gold Rush miners in the 1800's to modern craft brews pouring $3 billion into Colorado’s economy, beer has either borne witness to or helped create some of the most interesting chapters in the state’s history. Meet the pioneers of this now booming industry. Cheers!

SUPPLIES AND INGREDIENTS:

  • ½ cup 49 Volume Hydrogen Peroxide (*3% solution, first aid quality, will work … it produces a smaller reaction)
  • 1 TBSP liquid dish soap
  • 1 packet (1 TBSP) Active Dry Yeast
  • 4 TBSP warm water
  • Plastic Cup for mixing yeast and water
  • Food coloring
  • Plastic soda bottle (*16 oz. - 1 liter)
  • Washable or protected work surface
  • Foil Tray with high sides and/or Larger cookie sheet or tray with sides
  • Funnel (optional)
  • *Safety goggles (*or … ski/snow goggles, swim goggles) … for general eye protection!

DIRECTIONS:

To make up a batch of hippopotamus toothpaste …

  1. Place the soda bottle in your tray(s) … on a washable, protected surface.
  2. Pour 150 ml (½ cup) of 40 Volume Hydrogen Peroxide into the soda bottle.
  3. (You might want to use a funnel for this!)

  4. Add 1 tablespoon of liquid dishwashing soap to the bottle.
  5. Pour the packet of yeast into the small cup.
  6. Pour 4 tablespoons of warm water over the yeast.
  7. Carefully swirl the cup around to further mix the yeast and water. *It should be the consistency of melted ice cream. Allow about 30 seconds. Add a bit more warm water, if needed.
  8. Dribble several stripes of food coloring down the inside of the soda bottle. This should produce stripes, just like you might see in real toothpaste.
  9. Pour the yeast solution into the soda bottle … and stand back! Watch the mixture expand and foam up.

*Once the chemical reaction is complete, you should have (mostly) just soapy water and yeast. However, if you used the Volume 40 product, and some of the peroxide was unreached in the experiment, it could irritate skin and eyes. For that reason, it’s
recommended that you don’t play with the foam! And DON’T BRUSH ANY TEETH WITH THIS FOAM!

How It Works …

Each tiny foam bubble in this chemical reaction is filled with oxygen. The yeast is a catalyst, a substance that speeds up a reaction. It quickly broke apart the oxygen from the hydrogen peroxide … and that created lots and lots of bubbles! Your experiment not only created bubbles, but also heat … that makes it an EXOTHERMIC reaction.

Clean Up …

It’s safe to use a sponge to wipe up foam from your table surface, and just wash the remaining liquid and foam from the bottle and tray down the sink drain.
