Pool Noodle Water Wall

Pool Noodle Water Wall is a fun summer activity for toddlers, preschoolers or kids of all ages! Turn those extra pool noodles into a fun STEAM activity this activity!

This is a super fun and easy way to keep little and even big kids occupied this summer. All you need are pool noodles and string. I created our water wall on a fence. When creating your water wall try and find a vertical surface that has slots where you can thread the twine or string through.

Supplies for Pool Noodle Water Wall

• Pool Noodles
• String or twine
• Funnels
• Buckets
• Bowls
• Large Measuring Cups or a small jug

How to Make A Pool Noodle Water Wall

Use the twine to secure the pool noodles to the fence. Insert the fennels into the top of the pool noodles and place a few large bowls or buckets under the noodles to catch the water.

I filled a few buckets with water and handed my little ones some large measuring cups and other containers such as a jug and let them pour water down the funnel and watch it come out the other end!

How they Played

They loved it immediately! My 7 year old too. She was testing out how fast the water poured down each noodle and filled up the buckets and bowls below.

My 3 year olds used trial and error to figure out how much water to pour at once so that the funnel didn’t over flow. This was definitely a fun way to keep them entertained in the backyard this summer!

Water Wall Variations

1. Color Mixing Water Wall

Add a little science to your water wall by using colored water. Fill several watering cans or squeeze bottles with red, yellow, and blue water, then encourage kids to pour them through the pool noodles into clear containers. As the colors combine, children can observe how primary colors mix to create new colors while experimenting with different water paths.

Extra Materials: Food coloring, clear cups or containers, squeeze bottles or watering cans.

2. Water Wall Obstacle Course

Challenge kids to redesign the water wall by adding small obstacles that change the direction or speed of the water. They can clip plastic measuring cups, small strainers, or colanders between sections of pool noodles to create splashes, waterfalls, and slower-moving streams. Encourage them to predict how each obstacle will affect the water before testing their ideas.

Extra Materials: Plastic measuring cups, strainers, colanders, zip ties or clips.

3. Sponge Water Wall

Swap the pouring cups for large sponges soaked in water. Kids squeeze the sponges over the top of the water wall and watch the water travel through the channels. This version strengthens hand muscles and fine motor skills while still exploring gravity and water flow.

Extra Materials: Large kitchen or car-wash sponges, bucket of water.

Frequently Asked Questions

1. What can I use instead of pool noodles?

If you don’t have pool noodles, you can create a similar water wall using rain gutters, PVC pipe, cardboard tubes, plastic bottles, or recycled containers. Combining different materials can make the activity even more engaging as kids test how water moves through each one.

2. Can you leave a pool noodle water wall outside?

Yes! Pool noodles are designed for outdoor use and hold up well throughout the summer. If possible, store the water wall in a covered area or garage when it’s not being used to help it last even longer.

3. What age is a pool noodle water wall for?

A pool noodle water wall is perfect for toddlers, preschoolers, and elementary-aged children. My kids are 7 years old and 3 years old (twins). This activity is great for toddlers 2.5 years old and up, with assistance. Younger kids enjoy pouring and watching the water flow, while older children can design new layouts, test different pathways, and solve engineering challenges.

4. What skills does a pool noodle water wall teach?

This activity introduces early STEM concepts like gravity, engineering, cause and effect, and problem-solving. It also helps strengthen fine motor skills, hand-eye coordination, and critical thinking as children experiment with different water paths.
