Just like baking soda and vinegar simulate a volcanic eruption, baking soda interacts with acidic ingredients in doughs and batters to create bubbles of CO 2. But instead of spilling out of a ...

Toy submarine powered by baking powder. A baking powder submarine is a plastic toy submarine that dives and surfaces with the addition of baking powder.Baking powder submarines are sometimes misidentified as "baking soda submarines"; however, baking soda alone dissolves but does not react when placed in water.
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.
Fig. 1. Two balloons are connected via a hollow tube. When the valve is opened, the smaller balloon shrinks and the larger balloon expands. The two-balloon experiment is an experiment involving interconnected balloons. It is used in physics classes as a demonstration of elasticity.
Carefully hold the balloon opening under a faucet and slowly fill with water. Then gently pinch the neck of the balloon near the opening and tie a knot. Repeat the process with the rest of the ...
In the experiment, a film canister is filled with water, an effervescent tablet (commonly Alka-Seltzer) is added and the canister tightly sealed. After a short time, the pressure of the carbon dioxide is great enough to cause the body of the canister to be launched into the air with a popping sound. The canister may be embellished with paper ...
A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
