Buoyant Bubbles
Source Institutions
What keeps bubbles and other things, like airplanes, floating or flying in the air?

Bubble Cups
Source Institutions
In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

Bubble Bomb
Source Institutions
Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!

Big Bubbles
Source Institutions
How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

Anti-Bubbles
Source Institutions
In this activity, learners will be making the opposite of a bubble, an anti bubble! This low start up activity is fun, informative, and best of all-a little messy!

Bubble Geometry
Source Institutions
In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

Bubbularium: See the Colors in Bubbles
Source Institutions
With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

Why Are Bubbles So Colorful?
Source Institutions
In this activity, learners explore why they can see colors in bubbles and why they change.

Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.

Wind Mapping with Bubbles
Source Institutions
Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

Soap Film on a Can
Source Institutions
The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

Observing Cells
Source Institutions
In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio
