Welcome to your Everlasting Volcano Wow-To Guide!
The Everlasting Volcano is a model of a real volcano, to help us see how real volcanoes erupt.
And in this guide, you’ll learn about everything you need to create three different types of eruptions!

COLOR-CHANGING SLIME ERUPTION

1 Place the volcano model on a flat
surface with some newspaper or paper towels under it.
2 Remove the lid from the container
of slime. Fill the crater of the volcano to the brim with slime.

3 Press the lava lever down. The
crater will bulge upward a little.

Press the lava lever down a few

more times until the crater pops

up and the lava erupts down the

sides of the volcano!

Press the reset button

and push the crater

back down to reset the crater after the eruption.

Hold the slime in your hand for a couple of minutes. Do you see it

change colors from reddish orange

to yellow? Also try warming up or

cooling down a metal spoon under a

faucet and touching it to the slime.

Wgoohnianhtge’sre?

The volcano pops up because there is a machine inside of it that pushes the crater upward a little bit with each push of the lava lever. You can see how this machine works on page 7. This models how
pressure builds up inside a real volcano, causing lava to erupt out. The slime changes color because it contains a special pigment that
changes color based on its temperature. Read about this on page 6.

RUBBER BALLS ERUPTION

1

Place the volcano on a flat surface.

3

Press the lava lever down. The crater will bulge upward a little.

Press the lava lever down a few

more times until the crater pops

up and the rubber balls burst out

of the volcano and rain down.

Press the reset button to reset

the crater after the eruption.

2

Place all of the rubber balls into the crater.

“A gigantic Earth pimple”

Wgoohnianhtge’sre?

The mechanism inside the volcano caused the crater to pop up and eject the balls. This models how rock fragments called tephra are
sometimes ejected during the eruption of a real volcano. Large
tephra pieces are called volcanic bombs. When these fragments are

airborne, they are called pyroclasts. Read about the different things

that can come out of a volcano during an eruption on page 9.

VINEGAR AND BAKING SODA ERUPTION

1

Place the volcano on a flat surface that can get

messy. Put newspaper

or paper towels under it.

Fill the beaker as follows: first, to the
3 10-ml mark with dishwashing
detergent; second, to the 30-ml mark with water; third, to the 90-ml mark with white vinegar; and finally, add 20 drops of red
food coloring.

2 With the beaker, measure
10 ml of baking soda. Pour it into the crater.

4 Pour the liquid from the beaker onto the
baking soda in the crater. The mixture will immediately foam up and erupt out of the crater. Note: You do not use the lava lever with this eruption.

Wgoohnianhtge’sre?

The mixture foams up vigorously because the vinegar is an acid and the baking soda is a base. When acids and bases combine, a chemical
reaction that releases carbon dioxide gas occurs. The dishwashing
detergent surrounds the bubbles with a protective layer, making the

bubbles last longer, resulting in the foam. These bubbles don’t contain

normal air, but rather carbon dioxide formed from the reaction.

COLORS-CLIHMAENGING

iyt”‘oOsurlaagvnlaagd?e”

The slime in this kit is thermochromic
which means it changes color due to a change in temperature. A
thermochromic material changes
color because when it is heated,
its molecules absorb and reflect light in new ways. This process is
reversible because it does not involve a change in the structure of
the molecules in the material. This type of change is called a physical change. There are two common groups of thermochromic materials: liquid crystals and leuco dyes.

Liquid crystals
As the name suggests, liquid crystals are
materials that are in a state between a liquid and a crystal solid. When the crystals are cooler, they are further apart and they reflect light in one color. When the crystals are warmer, they move closer together and they reflect light
differently, thus appearing as a different color.

WHITE LIGHT

RED LIGHT

COOLER

Leuco dyes
Leuco dyes are chemicals that
can switch between two different forms, one of which is colorless, depending on exposure to light, heat, or pH. These dyes can be mixed with
other pigments to show one color when they are warmer and another color when they are cooler. The slime in this kit contains a leuco dye, as do
color-changing plastic spoons.

WHITE LIGHT

ORANGE LIGHT

WARMER

Liquid crystal surface

A classic example of a thermochromic liquid
crystal is a mood ring, which changes color in
response to the wearer’s body heat. Another
common use for liquid crystals is in liquid crystal displays (LCDs), which are used in TVs
and computer monitors.

“Too hot to handle”

The volcano pops up because there is a vertical rod under the flexible pop-up crater that moves upward a little each time the lava lever is pushed down. This is because the other end of the lava lever presses upward on a tooth on the vertical rod. A device called a ratchet keeps the rod from falling down again even though the lever resets each time. A spring pulls the vertical rod downward while a small bar called a pawl prevents the rod from falling downward. The reset button releases the pawl, letting the vertical bar fall back down again and resetting
the crater.

What is a scientific model?
A scientific model is a simplified representation of a more complex thing from the real world. The model is designed to help demonstrate and understand the real-world thing better. Models are never perfect recreations of the original.

The pop-up mechanism in the volcano models how the pressure inside a real volcano builds up until it erupts. Here’s how a real volcano works.

too great, its contents rise up through the volcanic conduit.

TYPES OF VOLCANOES

7#

“The four

types of

volcanoes”

Cinder cone
Cinder cone volcanoes are
often smaller than other
volcanoes — with heights of ten to a few hundred meters. To form these volcanoes,
lava is hurled into the air,
cools, and breaks into individual fragments, called cinders. These rocks fall to the ground around the volcanic vent and build up
over time, forming a cone.

Composite
Composite volcanoes (or stratovolcano)
consist of alternating layers of cooled fluid
lava and cinders, which form the recognizable cone shape of the stereotypical volcano. Some of these are
among the highest
mountains on Earth.

Shield
The shield volcano is
flat and wide, like a
warrior’s shield lying on the ground. It is created by fluid lava flowing very quickly from its vent and spreading out over a large area. Some of
the largest volcanoes
in the world are shield volcanoes.

Lava dome
The lava dome is a steep mountain created by very viscous lava, which cools down quickly
and piles up around
the vent. This seals the vent like a cork, often making the next eruption even
more dangerous.

Lava: flowing molten rock
Volcanic bombs: tephra larger than 64 mm

Gases: like water vapor, carbon dioxide, and sulfur dioxide
WHAT COMES OUT OF A VOLCANO?

Ash: tephra smaller than 2 mm
Lapilli or volcanic cinders: tephra between 2 and 64 mm

Olympus Mons

The largest known

volcano in our solar

system is Olympus

Mons, a shield volcano

on Mars. It is 25 km tall

and 624 km wide —

about 100 times larger than Mauna Loa,

the largest volcano on Earth. Olympus

Mons appears to be inactive.
