Mentos and Soda Experiment Concepts

The video explores the phenomenon of bubbles forming on objects placed in soda, such as straws, pipe cleaners, and Mentos. It explains that carbon dioxide gas in soda forms bubbles on surfaces with tiny dents and scratches. The video also demonstrates a fun experiment where Mentos are dropped into a soda bottle, causing a rapid release of bubbles due to the large surface area of the candy. This is a practical demonstration of chemistry in action.

What happens when you place a straw in soda?

• The straw changes color.

• The straw dissolves.

• The straw sinks to the bottom.

• Bubbles form on the straw.

What is observed when a pipe cleaner is placed in soda?

• It sinks to the bottom.

• It changes color.

• It becomes very bubbly.

• It floats without bubbles.

What gas is responsible for the fizz in soda?

• Hydrogen

• Carbon dioxide

• Nitrogen

• Oxygen

Why do carbon dioxide bubbles form on objects in soda?

• Because of tiny dents and scratches on the objects.

• Due to the smooth surface of the objects.

• Because the objects are magnetic.

• Because the objects are warm.

What is a key feature of Mentos that causes rapid bubble formation?

• Its weight

• Its smooth surface

• Its large surface area with tiny dents

• Its color

What is the first step in the Mentos and soda experiment?

• Place the Mentos on the ground.

• Open the soda bottle carefully.

• Drink some soda first.

• Shake the soda bottle.

What should you do after placing the Mentos tube over the soda bottle?

• Remove the card to let Mentos drop in.

• Shake the bottle.

• Close the bottle cap.

• Pour out some soda.

What is the result of dropping Mentos into the soda?

• The soda freezes.

• A geyser-like effect occurs.

• The soda becomes flat.

• The soda changes color.

What scientific concept is demonstrated by the Mentos and soda experiment?

• Photosynthesis

• Chemistry in action

• Magnetism

• Evaporation

What is the main takeaway from the soda and Mentos experiment?

• Soda is a solid.

• Soda is not fizzy.

• Mentos dissolve in soda.

• Carbon dioxide causes rapid bubble formation.
