The experiments described in the instruction manual typically require a number of chemicals not shipped with the chemistry set, because they are common household chemicals: Acetic acid (in vinegar) Ammonium carbonate ("baker's ammonia" or "salts of hartshorn") Citric acid (in lemons) Ethanol (in denatured alcohol) Sodium bicarbonate (baking soda)

For parents, he pushed the idea that the sets' use of chemical reactions directed their children toward a potential career in science and engineering. [ 2 ] In 1954, Gilbert wrote in his autobiography, The Man Who Lives in Paradise , that the Atomic Energy Laboratory was "the most spectacular of [their] new educational toys".
This experiment is about much more than just watching Iodine solution turn royal blue from reddish brown. Try this experiment at home with the kids to introduce them to the basic tenet of physics ...
Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1]
The amount of solid chemicals dissolved in the experiment could be reduced from 60 grams to 6 grams. And the pH could be lowered from 13 to 3 which is easier to neutralize the pH to 7 by adding baking soda before disposal. [16] Also, it is safer and the reactions also occur faster and are easier to perform.
The experiment is practised in schools around the world and is often used at open evenings to show the more engaging and entertaining aspects of science in secondary education settings. [2] [3] The experiment shows the amount of energy there is in a piece of candy. Jelly babies [4] or gummy bears [5] are often used for theatrics.
Soda can have a big impact on kids in the short-term. "You get a sugar rush — there's an increase in blood sugar and possibly the effect of caffeine," Zaslow says.
