The awesome majesty of volcanoes

in a beautiful bottle

Two sizes — the original Regular size, and the Large, for bigger longer-lasting volcanoes
Interactively create volcanoes, including central cones, and dynamic channels of air and sand along the side of the bottle. See the air channels fill with colored sand!

Unique eruptions with every shake

Volcanoes capture the imagination. They are the connection between the earth’s surface and powerful unseen forces underground. We can only observe the surface features of real volcanoes, and have to stay at a safe distance from active volcanoes. But with Volcano in a Bottle, we can play with simulated volcanoes in a safe and interactive way. Shake the bottle and watch channels of gas form underground and erupt at the surface! What can you learn about our world by studying the moving plumes of sand? See the world in a bottle of sand!

To make a basic side volcano, follow these instructions. It is helpful to invert Volcano in a Bottle while shaking it to fluidize the sand well. See different patterns of volcanoes and air vents every time! After the eruptions subside, enjoy the colored sand patterns left by the lava flows.

More than just a volcano

Volcano in a Bottle is a miniaturized version of the earth’s crust that is safe and inviting to play with. What can we learn from these grains of sand? See geophysics in action — millions of years of volcanic action every 30 seconds! And no need to worry about clean up — everything happens safely inside the bottle.

No batteries required! No chemicals involved! Scratch and shatter resistant. BPA free. Volcano in a Bottle is patent pending.

Can you make volcanoes along the side of the bottle? Can you change the pattern of the magma flow and shift the location of the volcano vents? Can you make baby volcano vents around the rim of the bottle? Can you make the legendary “Central Volcano”? How can you catch “big air” in the sand to power more interesting volcanoes?
