HERES HOW

1. Roll the piece of paper into a tube so

that it ﬁts around the rolled pack of

Mentos candies.

2. Remove the Mentos from their wrapper

and arrange them to they are stacked

neatly inside the paper tube. The tube

should be loose enough for the Mentos

to move freely inside it.

3. Open the diet cola bottle and rest the

index card on the mouth of the bottle.

4. Align the paper tube of Mentos

vertically with the mouth of the bottle,

and hold it there, with one end resting

on the index card. The index card is

preventing the candies from falling into

the soda.

5. With one quick motion, remove the

index card and all the Mentos will fall

into the bottle. Stand back immediately!

Soda geyser

experiment

YOU WILL NEED

→ 2 liter bottle of diet cola

→ pack of mint Mentos® candy

→ index card

→ piece of paper

A reaction occurs between chemicals in

the Mentos and in the diet cola, causing

a massive release of carbon dioxide gas,

which foams up out of the bottle. The

shape of the Mentos also helps produce

the foam. They have tiny indentations all

over them that increase the surface area

for the reaction to occur. And, because of

their size, the candies get trapped inside

the bottle to continue to react instead of

being pushed out of the bottle by the

eruption.
