Bubble Bottles

Introduce scientific reasoning through a problem solving process that enhances their cognitive and critical thinking skills.

Create bubbles in a bottle while learning about science!

Children are natural born scientists. Activities where they are able to explore and experiment with several ingredients to see cause and effect happen right before their eyes creates inquisitive thinkers. 

As they pour, mix, and create the child will go through different processes that will challenge their critical and cognitive thinking skills.


For this developmental activity you will need:

Two Clear plastic bottles


Food coloring

Dish detergent


Duct Tape

Learning Outcomes




Observation and Inquiry, Physical Science Curiosity, Initiative, and Risk-Taking Creative Thinking, Problem-Solving, Reasoning


Using scientific reasoning to enhance observational and cognitive skills.


Step 1:

Fill clear plastic bottles about halfway with water.

Step 2:

As children watch, add different colors of food coloring to some of the bottles. Join children in watching the color swirl through the water.

Step 3: 

Add a squirt of dish detergent to each bottle.

Step 4:

Spread glue around the rims and fasten the lids securely. Wrap duct tape around the lids to further secure them.

Step 5:

Invite the children to shake the bottles. What happens? Shake some more! The children may also enjoy rolling the bottles back and forth.

Step 6:

Line up the bubble bottles on a windowsill so the light can shine through. Look at them from time to time

throughout the day. How do they change?

Playful Questions

How many bottles do we have?

What do you think we are going to do? 

Can you predict what happens when you mix soap and water? 

What colors do you see?

Can you shake fast? Slow? What happens when you do that?
